Also tried drawing technology, since I suck at it, hence, the cellphone next to him.

Upper right: Some ninja fox chick thing, Iunno, whatevs. Reminds me of the Viera from Ivalice.

Lower Left: Samurai mammal girl chick thing. It was another practice on perspective and dynamic poses and angles.

Lower right: Me and  cursedhand worked on some fighting game sprites. He wanted to try my character, so we came up with that.
One on the left is the more current one.
