Low quality is because I saved it as ''gif''
more splatter would ruin the bg.
How is the border messed up? Its a normal white border, black would make it hard to see and would give a more dark effect which would ruin my light source.
I use adjustment layers, and I sharpen my render and splatter for dept.
In fact I am improving my effects. I try tutorials for things like C4D's.
Further, I just try somethin', leave it if I lake it, adjust it if I don't. Untill I have a nice signature.
At the last moment I create a border, and i'm not cutting that step.
