I find it's a good way to practice observation and hand-eye coordination. One tip for you is to break down the subject into basic shapes like circles, squares, and triangles. This helps you establish the overall structure and proportions before adding details. Moreover, You could use your pencil or thumb to measure and compare lengths, angles, and proportions which help you accurately translate what you see onto your paper. Your drawing looks so great, you just set aside regular time for drawing and experimenting with different subjects and techniques. Over time, you'll notice progress and feel more comfortable with your drawing abilities.
i did use my fingers to make sure the t pose hands have same lengths (reaching about the upper half ot the thighs) like i meassure one half from the computer screen and do it for the other half :D
i think i usually just draw straight away by simplifying things first tho instead of basic shapes which are kinda abstract to me i tend to build a simple bone structure mentally instead. maybe similar to a stick figure as well. for these ones i remember starting from the hair and face since i don't usually have much trouble with them, and it's usually the clothes, hands and feet position etc. that i simplify, esp the clothes.
i do feel as long the general idea and vibes are there, it can end up looking better than if i force myself to draw all the painstaking details. at least i can wait until i can draw them comfortably first.
though yea, it's a good idea to experiment with different methods and spice things up more. back then i did the usual sketches over and over and got bored quickly lol.
i did draw for a long time though, probably why the sketches look decent :D
thanks for dropping by and for the tip as well
