Was gonna post my spitfire cutaway, but thats school so i did somethin' else.
When im stuck i do a self portrait to experiment. I find its easier to play with tools, colours or composition when I'm dealing with more familiar subject matter.
Photoshop and a mirror

also painted these two buggers, the environment is repainted school project, tryin to fix it up for portfolio. Its got some big compositional issues but i still kinda like it.
