First anime sig. Still in that awkward first stage, where all your first five or so signatures are terrible. Still have the .xcf, so suggestions on what to do next would be helpful.
I liek how you used color on the eye to create a focal, but I'm finding the smokey stuff on the left to be too distracting. Maybe blur that a bit more.
I like the signature. It has good flow, depth, and the focal is defined correctly. The replication to the right doesn't work for this signature and is rather distracting. The flame is too much. It does add and help the flow, but the flames towards the left doesn't. The signature also needs a better blending, and a light source. Other than that, great signature.
I don't like how the smokey C4D is kind of covering his neck, it seems like its almost a floating head. Perhaps show us a colored version?
