You have a good eye for color but your figure composition is shaky. You need in my opinion to do many more studies, rough, fast studies from real life reference. They can be in pixels, I don't mind. But they need to be from reference so you (and we) can check where you're deviating from what you're seeing. The face here for example looks realistic but only in passing. Once you look closer, the facial features are well rendered but they're on a flat plane, with a forced perspective, one eye bigger than the other, the construction of the head hidden by messy pixel clusters and hair. I know all these signs because I used to draw like this, and still do to some degree. You need to do more, structurally. Trust me.
If you drew on paper without pixelly tech to make everything pretty, you would see very clearly where you're lacking in figure drawing. The anatomy is 'semi-there'. This is good because it means you have an instinctive understanding of it. But it's a bad place to say in for a long time, I know because I was and still am in a way. I think you're young (correct me if I'm wrong) so all the better to get on real figure drawing and push yourself there, not just pixel technique.
