looks plain because I match brushes with renders color.. I think thats why.. and I added couple brushes but made them render color and black.. and I'm reading tuts for C4D now.. so I'll be posting C4D sigs now.. ands for feedback =]
work with some other colors too that also compliment the render...
work on creating depth, light source and blending too...
and you dont have to make c4ds... there are soo many great ones already made that you can easily get your hands on
