Well, I'm done. Sorry, I chose to do pixel art because I didn't think I would do it any other way. I do digital drawing most of the time, and with my mouse, so you see the image. : D
Other than that I tried to do my best but didn't have the courage to tackle the shading and everything. And some of the anatomical parts like the ears, the nose (I managed to do the nostrils on a stroke of luck), the mouth are doubtful, because I have not yet mastered it well. In fact, I do not master portrait drawing in general.
If not, maybe I'll try again ... someday.
