It's way to purple in my opinion, in general I don't like the use of photofilters or curve layers like that. It makes your sig really over contrasted and unbalanced. And I think the sig is way to messy, especially in abstract art I like it clean with a nice flow. I think the main problem here would be the c4d's chosen, some part really don't fit with other parts.
curve is great if you know how to use it. and in some instances people don't mess around with the b/c and the piece comes out very flat. I agree though it seems overdone.
I have to agree with this. Minus the curve part. I use it too colour my signature when i'm done with them. Just playing with the red/blue/green channels i find brings out a better colour scheme.
