Cute character but I dislike the middle finger, kinda rude to the eye.
The anatomy is also wrong, it is like you designed a girl then removed the boobs. A trans person will never ever look like that without some extremely advanced and painful surgery. The main difference between guys and girls in anatomy is that girls have larger hips than the chest area, while the sizing for guys is pretty much equal with the chest. The reason for that is that real women have to give birth and host children there beforehand.
The lower leg also seems wider than it should be.
Just my 2 cents, you know more about 2D art since you mainly do that while I do 3D art, but I have studied anatomy and what I said is pretty much the basics.
Edit: oh, it is the other side of trans, gotcha
