Artist looking to build portfolio

I am a dedicated, creative, and reliable artist ( and history/language student).
I am willing to work on any 2D or 3D art you need for any game. I am still building skill in both areas, but I am far more skilled in the production of 3D art, striving for good shape and an efficient polycount. I am a firm believer in experimentation and dedication to improvement in form and style, regardless of skill.

Anticipated downtimes are considered to be about half of the gamejams (such as the upcoming Molydeux Jam), and between 28th August and 28th of October, while I move back home to the UK, begin the new academic year in university, and get used to the demands and routine of studying History and Russian.
