Hahaha my first attempt ever at a sprite. EVER. I did a bit of cheating here, to be honest lol
Borrowed body parts from several trainer sprites (mostly from Pokemon Diamond sprites) and merged them together. Soooo hopefully I'll have a trainer card soon!
The actual shape and details of the sprite are fairly decent. I would work out the arm proportions and torso shape to be a little more true to your artwork of this character. I also suggest experimenting with darker and lighter tones of the colors used to give her proper depth, so you don't have such a flat sprite. All of this said, for a first attempt, this is impressive.
