Karkat's in Doubt

Okay, the only reason I'm writing this is because I do not agree with the previous critique.
First of all, I'm fine with the simplicity of this. A whole bunch of fancy shading would look cool... but you know what? I think it's fine the way it is. It just kind of "stands out".
The horn shading is nice, and I think that's a strong point of this drawing.
The symbol on Karkat's shirt is accurate. You drew the table very well, though I feel like the movement line was unnecessary. The head is too big for the body... but it gives it a comical affect. And I like it.
I feel like you could've made the hands look more clenched by actually adding fingers. And the eyes are a little too bright yellow.
But overall, great job! I hope I helped.
