no I think it looks great : 3 You did a really good job with the proportions, I only have 2 segestions to make it even better. The first of wich, is I think you should take out the top line that marks the top of the shoulder... only because by doing this, it makes the shoulders really look like its a separate piece from the body(isolated from the body), when really its only the arms that apart from the body not the shoulders, so yea I think if you take that out it could really help your image look better. : )
Also I know you don't want to add shading but I think that the image could really give us more that "wow" factor if you lightly shaded a bit, just to give your forms more volumes. Cause right now your image looks kinda flat but thats only because you didn't put any shading. I think if you put a little shading, just in the shadows to help creat some volumes in your image you can really make it stand out more
3nodding Now I understand what you mean about to much shading on it makes it look gritty and stuff, so I just found you a couple examples of how you can do it lightly just to show off some volumes and forms with out it getting

You did a really great job on your drawing and I can't wait to see some more of your work : 3
