Finished the tutorial and given it out for free together with an other tutorial of me http://www.gamerenders.com/forum/index.php?showtopic=339896
Background looks too random (you have these issues allot with IRL people as render) and the render needs some blending. Maybe chance the colors of the background to abit more brownish? I think that would suit the render. Also, the bright part at the left side of the render needs to be cleared away imo, it takes away the lighting. Just some constructive critism
