V2: My 3rd abstract sig. This time I used brushes I found as well as C4Ds that I made just for this sig. CnC.
That is one of the C4Ds I made, but it is set on Screen or Linear Dodge, so parts of it aren't visible. I will update it in a second. Edit: V2 is in the original post. It seems a bit lacking without a strong focal point, because now it is just outward flowing C4D effects...
