That signature is really cool. I like the C4D effects and the render. It might be nicer if it was darker in the bottom left corner though.
It is a little bit too much. The flow is alright and the depth too, I like your text as well but the lighting comes from multiple points and does not look very real. Plus the messy thing, you got better work man. ^.^
Meh...I just found the wallpaper and started throwing things together on Photoshop Canvas. I haven't done any art in past five or six months... Thanks though.
