Hey MJ, I agree with @Simon L about the background, and the overly soft brush work. I would add a few specific things that I noticed. The drawing has some proportion issues, some of which it looks like you fixed in the painting stage. I did a quick sketch over your drawing, without the reference, but just what I think looks correct. You'll see I made the leg longer, defined the lower leg, and added mass to the head and thinned out the neck. Also, the chest you drew doesn't relate to the rest of the torso, in other words, it looks disconnected to the rest of the body. The rendering problem I noticed has to do with how you draw the core shadow. When you make it the sharp of an edge, it really flattens out the form. I did a quick painting of the arm to show you how adding transitions in and out of the core shadow helps turn the form in a more convincing way. I hope this helps :)

Hi, nice work! I'm not competent enough in anatomy to feedback on that, I can however give some thoughts about the digital drawing. The main issue for me is that the texture in the background is in focus, whereas the character isn't. Also, be careful when using a textured brush over parts that are blended, now there's sort of islands of sharpness in the drawing (where the textured brush has been used). Don't blend/smudge everything, that's when you get that "digital" feel to it, instead, commit to values and planes and blend in the transitions. PS I blurred the background, see how the eye is drawn to the character and not to the right side of the picture :)
