Ok, some words of advice. Her torso is a bit too long, I'd like to see it shortened a bit, the right hand looks kind of weird, I'd look up photos of people holding tennis balls or something similar and see how it looks. I see what you were going for with the face but I'd steer clear of facial expressions for now, just make it neutral like you did with the previous one. And lastly, the colours are way too saturated, perhaps make them more grey. Greys connect colours very well. I can see the effort you're putting in it and I didn't want to see this post not recieve any feedback. Keep drawing and cool things will happen for sure. Cheers.
