This is one of the best rendered models I have seen. I did a double-take when I saw it was in the "Rendered" section. I will agree with auto-nut, though, that the mirrors need a little work. This is an outstanding piece of art nonetheless.
I was testing as a journalist this motorcycle few months ago, and i really liked it. Nice looking yoshimura exhaust. Nice looking rear brake disc. MAybe You could add alsoi wave discs in front? The only thing I notoced that does not look real is front brake lever.
But still: great modelling, great texturing, and great rendering.
Awesome detail. I think the bars that hold up the rear wheel need some extra textures. Looks too perfect. Maybe a slight reflection or some scratches/dirt. The brakes and suspension are amazing. love the detail and realism. Great work there. The seat needs some work. Try a crease bump map or adding some stitching to it. Other than that Amazing work. Love the texture and modelling detail. Your backgrounds are the greatest. +fav, kickass work.
