Really like the look, I feel like the picture was taken from an angle and that’s throwing off the perspective to me.

There’s something about it that makes it look flat and I can’t quite figure out what, It’s not the hair because that definitely pops. I think it’s maybe the need for some sort of cheekbone or something?

Hmmm…

I know it’s just a sketch, but I always found that holding my pieces up to a mirror helps out a ton when I’ve been staring at a picture for a while. You can see mistakes and such much easier. Keep up the good work friend!

I read that as Euthanised, i hope you get better :D

The face is lopsided. You can see this thanks to the double red line. It goes through the chin but not the middle of the forehead. The entire right side (our perspective) is higher. Especially the eye will trigger the “something is off” response. The shadow to both sides of the neck suggest light from the top/front, but then the nose would need appropriate shadow as well. The mouth sits too low on the face.

I recommend using the Loomis method to learn how to draw the shape of heads. You need to understand the mass you are drawing, not just single parts of the face. Right now, you are guessing shadows and placements based. Google Loomis, it’s a very popular resource for learning to draw faces and heads. Loomis also shows very cartoonish variants, which is more in line with what you are going for (rather than realism), which I think could help.
