Boss render mate. the background is great but it still seems very separate from the render. There is a very clear foreground and background. Some blending between the two is needed. Otherwise it looks sick
Very nice Sinsation! I like it. However, I think se7en ace has a point about the foreground object as appearing too distinct. Not that I'm an expert in this at all, but maybe some degree of feathering, or some other appropriate tool would soften the edges and make it blend in better. Otherwise great job!
