Remember what I said about bilbo's coat? Well you didn't do it hear. His jacket looks like a starchy two dimensional piece of paper. The red inner clothing looks fine. You seem to draw well with red over other colors. His face has issues I'm willing to over look because this is your best face so far.
The only lazy parts on the head is where it's shaved on the top left (really lazy buzzcut there) and his neck has way too much light exposure. His body is way too big but it kinda looks good here.
The books in the back and the shelf they are on are rubbish, as is the shading below them.
