There's a bit of general wonkiness in the whole piece that I feel you should address before going farther with this. Like for example the crown, I get both the feeling that the peaks are unevenly aligned somewhat, plus that the front side and back side are both completely different looking.
Furthermore, some things just feel off. The light is coming from our right but the torso LOOKS shaded from the front (even if it's shadowed by the cape, the impression's still there)
You should use shading to define shapes and detail a bit more since you're not going with outlines. Let's see some more shading in his face, put some of those darker shades on his left(ourright) side so it looks more clear. Also some more symmetry would be nice, after all a king should have a competent barber, so make sure it's even and symmetrical.
That and ... Maybe fuzz up the fuzzy brim a bit so we get that it's furry!
...
I dunno what to say more! I hope I'm not coming across as too harsh or anything, cause I really think this one has potential, and already looks nice. Also please do check out skamocore's edit - on my screen it looks almost monochrome, but in all it's dullness it's much easier on the eyes than the signal red you've got going on, so work some on that too!
Good luck!
