Actually the face looks lil bit flat to. Add shadows on the suit , you have the same contrast and color all over the suit. Try Selecting the suit and apply dark dull layer of color, mask it and erase where the light falls on him. Darks and lights reveal the the 3d feeling. I hope I help.
This time Im gonna leave the design ,but do your best to present the characters , light them , shade them , do something interesting for the viewer, give the characters some life , expression "character" ,because if you are doing book with this kind a pictures ,am sorry but im losing interest after 3 seconds when i see it. You need stringer fundamentals. I hope I helped you, good luck :)
Hey yeej9354, I think your getting a little ahead of yourself here. There are some very important steps that you have yet to master before moving on to anatomy. It doesn't do us any good to move forward in a drawing if the pose and structure are not accurate. That is why the gesture and structural drawing is so important, that's where all the hard work is done. That is where we work out all are problems and issues. Only after we have done that, do we move on to the more refined parts of our drawing like anatomy and rendering. I did a drawing to show you what I mean. I hope it helps you :)
Hi there ,I like it and my opinion is: its pretty clean there is not much to say. It looks like its gonna be a sheet of turn around's like a concept artists do. I would try something different like turn his head towards the camera and and a little bit tilted and do his face expression somehow angry or something. Also I will love to see his arms anatomy a bit more and maybe give him some tattoo on one of the hands.Bulk him a bit. and (bear paw from his "cloak" ? bear skull on his waist ? ) Its clean, but a bit generic, go wild! good luck :)
