I feel bad about abandoning this thread, so quickly popping in again for some fast feedback. I am however, seeing a lot of the same flaws being repeated, so a bit of general advice first:
A good synopsis will tell potential readers why they should invest time in your story. That means it will often answer at least one, sometimes two or three of these questions:
- Who is your protagonist, and why should I care about them?
- What are they trying to achieve, and why should I care about that?
- What is preventing them from achieving their goal?
- What sets this story apart from the dozens of stories with a similar premise?
Another thing to keep in mind is that you want to use all of the tools you have available to attract readers: cover, title, tags, and synopsis. If all your synopsis does is dryly rehash what you've already stated in the title and the tags, then you haven't used the synopsis to its full potential. A synopsis should provide extra incentive beyond what title and tags can deliver.
Now, on to the crits:
professional pianist, practice every day, owned since I was a little boy, fairly skilled, make a living in orchestra and concerts. That's a lot of different ways to mostly state the same thing, and after all of that, I still don't know anything more about your protagonist than that he plays the piano, and that he's probably self-centered.
Beyond that, the latter part, aside from being barely more than a repeat of your title, is actually surprisingly solid. It's blunt, it's deadpan, and that's what makes it work. It's a very unapologetic, tongue-in-cheek way of stating, "yeah that's really all this story is, so sue me. I'm writing this and I'm having fun with it"
It's not really my style of synopsis, and secretly I'd like something a little more fleshed out, but for the kind of story you're going for, it's perfect. Just, maybe doing something more with that first paragraph.
Lonely kid, sad youth, suddenly superhero powers. The problem with that summary is that it sums up the backstory of the vast majority of superheroes out there. You need to say more, state why this is different than all the others.
Kamen Rider stands out, but it's not super-mainstream and thus suffers the same double-edged sword fate as fanfiction: likely to pull in fans of Kamen Rider, likely to scare away anyone who doesn't know what it is. Not necessarily a negative, just something to be aware of.
That leaves "Written in a poetry-like structure" as the only stand-out element of the synopsis. I like it. I really like it. It is daring. It contrasts nicely with the superhero premise. No one expects
the Spanish inquisition superhero poetry. Know that it might be a little too daring for the Scribblehub audience though, likely to scare away some readers with flashback nightmares to high school poetry assignments.
This one is a little rough, but underneath that roughness lies a spark of something brighter. The underlying premise is a generic fantasy adventure, yet it projects the feeling of a more honest, more sincere, more exploration and wonder-filled, less testosterone-laden execution of this basic motif.
The details of the synopsis require a bit of work though, often evoking more honest confusion, than a general interest in me. It just has this weird combination of tiny little details and incongruent broad strokes.
The protagonist has such a weak constitution that she can't leave the house but goes adventuring anyway. How does that work? is this Raph's doing? Raph is a rather generic name for someone described as a "mysterious entity". So what makes him mysterious then? Clara was tricked by Raph but was housebound before that. Does that mean her mom was taking care of her? What do her caretakers think about this Raph's intrusion and almost kidnapping of Clara? And then on one hand Clara was deeply affected by her father's disappearance when adventuring, on the other hand, she simply goes out adventuring herself, and it's apparently not related to her father's disappearance in any way?
A good synopsis is supposed to evoke some questions and pique the interest that way. But this one evokes too many of them. So maybe tighten that up a little bit, focus on one to three big questions you want your potential readers asking, instead of "all of them questions".
First impression: classic reincarnated in my novel/game premise, but with some tiny twists: local wildlife appears to know he's the creator of the world, and someone/something messed with the system and bolted a PvP on top. Those two details hint at you doing more than just a rehash of the same tired premise. But then you end it with a generic sentence that appears to ignore these little extra details. So this just leaves me confused: is there more to this, or not?
This confusion leaves you without standout elements. The premise might be generic, and besides their name, we know nothing about your protagonist or their goals. So I'm going to advise you to think a little more about your hook here. What are your standout qualities? What is supposed to draw the readers in?
