This is something I just recently did. I am unhappy with the end result. The anatomy of his upper left leg is ****ed and his abdomen is positioned awkwardly in comparison to the rest of his body and the values in his red underwear doesn't help with that, either. Also, I didn't want to put much focus on the cape, and that shows.
OH WELL! I plan on doing another super hero drawing. But probably with different media. Just thought I'd show you all so you know I'm not dead.
So I'll start this off by touching on the most fundamental things, and then start going more and more into nit-picky detail.
There are problems present that developed in very early stages, so what I recommend you practice most from what I see from your results are the first and foremost figure drawing steps, before details, or even structure becomes a thing. Everything is going to be built off these first steps and without them, you'll miss things like force, movement, anatomy, structure, all which come together to create a natural looking pose. Right now, your pose is very rigid and artificial, suggesting you either didn't start off mapping everything out, or you jumped ahead too quickly into structure. You probably are at least somewhat aware of figure drawing steps, but just to re-itterate, I made a small and simple tutorial a while back of the making of one of my drawings. It might help you with basics a bit.
So moving on to anatomy, it looks like everything important is
there, just not all in the right place. The fickle thing about anatomy is that it starts to look kind of silly when you draw too much attention to it. Instead of making everything structured with lines, you'll be better off leaving that job to shading and color. At the very least, don't have lines that are so thick show everything off. Lines are best suited when they help create and emulate the feel of a third dimension, and since life doesn't exist with outlines, drawing a single line to represent a bicep or an abdominal region. This is best show in superman's thighs and kneecaps, where you've allowed shading to take place of straight linework, and you've defined the kneecaps with more general, organic lines. Compare this now to his right arm, which does the complete opposite of both these things, using a single oval to define a bicep and leaving the colored pencil shading to do nothing but create egg-like bumps underneath his skin. I think if the entire drawing was done in the same fashion as the legs were done, it would be 30x better at least, overall. That being said, the lines in the legs do seem a bit thick and dark, kinda like you were going for an inked look and then bailed last minute.
Onto colored pencil usage, I'll first say that they take a whole lot of patience, and they really need time and care, but you know this already. I still have to say it though, because a single part that looks hastily done, or any time there's not enough layering going on, it shows. I'm talking about the cape, but you probably already figured that out too. Impatience happens, but it really drags everything else down with it, which is a pity because colored pencil is so permanent to work with and there's no reversing a lot of the times.
Next time you work with colored pencils, start with the darkest regions first. The pitch blacks and the dark blues/purples will be there by the end no matter what layering you use, so they go first. Keep your pencils sharp, because they become less consistent and get nasty textures if you don't keep them in good condition. Keep your pencil strokes neat and tidy, following the curvature of the surface and building up in darker areas. A well done colored pencil drawing should have no less than 20 layers of different colors and shades working as gradients and blends to make a much more vast array of colors than the 24 or so that you initially are given in a package.
You're all awesome annnnd
