This is very nice Artwork. Well done. The look in her eyes is very well . Looks like that she will frighten her opponent. The pose says also, I WILL BEAT YOU. The crowd in the backround is well done, a good mix between heroines and normal visitors that watch the match. You have put a lot off nice details in this pic. The gold applications on the bikini , the holes in the gloves are nice and gives the pic a realistic look. Also the rust on the cornerpost .
Go on with this stile, i would love to see more off this.
