I think that even on your off days, you're a much better artist than I am. I'm barely able to draw pony legs, and faces are impossible for me. Tess still looks amazing here, even if you derped her eyes.
Practice makes best, right? It's been a rough journey for me to get even this far. Just force yourself to improve. Don't let go, ever. Failure won't be an option. Keep telling these things to yourself while you draw. And above all, enjoy what you're doing.
Derped..? I was going for a freaky expression intentionally...
I took a look. Legs look quite fine, oh yes. You did say you had some trouble with the face. But you'll get it right yet.
For me it helps when I visualize the structure of what I aim to draw. Piece by piece. And when I think I know how each part is formed, then I just draw it in any position I want. Try that. I recommend drawing the parts on paper from different angles. Just focusing on one part at a time, and then expand into combining them.
