The anatomy is all messed up. It's an OK start, but the model is a bizarre mix of male and female characteristics that just doesn't work.

For start is not too bad,however in time I will I improve.

This is Motoko Kusanagi right?

Face and armor are different. Not Motoko Kusanagi from Gost in the Shell. Although, the "Stand alone Complex" in the background puzzles me. Probably was inspired by Ghost in the shell, but it is unique enough not to be fan art. There can be many different short purple haired women with badass armor.
