Well, imperfections can be beautiful, and what do we have here? Although I myself cannot see any imperfections at all, this certainly is a very beautiful piece of work. You did a wonderful job on this, so don't be too harsh on yourself!
I don't think it's a sad attempt at all Beautiful drawing, I love the amount of detail in the face and in the cloths. Despite what you say, the face is very nice, the one thing that maybe is throwing it off is the eyepatch, because you barely see any of it and it flattens that area of the face. Beautiful work though!
