What I can suggest is changing the design on the book, and on the inside, but remember that page gets mirrored. His belt buckle looks very good, is it like that medieval archery rose thingybob? The platemail is good except it looks too white, it could use darkening. The chainmail on his leg is good. Next time could you please attach the original wrap so we can easily compare. Yes, shading on the hair would do well. Other than that your skin is of good standards! +Rep.
