You said you liked criticism so here is a little. you shaded in the shirt way too much my man and this is just a suggestion but it would really help if you did just one solid outline instead of many micro scratches. and with the style you are going for there is this cool thing you can do where you outline with a shade of the color you use most in the drawing but a different shade, one last thing. it's a bit blurry, get it a bit sharper.
