Hello!
here are models for my portfolio, currently only high poly

black widow motor based on concept Solifague Design and Uaz

and sheridan

more on my blog;)

I don't find pleasing to look at models displayed with a skylight and Gi.Throw in some grey material with some specular and gloss, basically imitating a clay, a spotlight or two and then you can put the skylight and gi but they don't have to be that powerfull.
