It actually does have a flow. The yellow is going in a "\" type of direction in my opinion. Good sig, could have been done better.Well the render used is a bit blurry to begin with.
Lacks flow. It looks like the yellow is going everywhere instead of one direction.
Work more with adjustment layers. The lack of it doesn't make the sig bad, but it could definitely improve it.
It's missing a light source.
Also, came here looking for porn. Left disappointed.
