Manga's Hell Cnc, see you on the other side!
The signature just seems over LQ, I just don't like the c4d or render used, they don't seem to go well together. There is no actual light source, the light is sort of just there. It also does not make sense in terms of it just randomly ends in some areas. The depth is okay, not great but not bad. Signature doesn't seem very proportional (due to the background). Blend is fine. Text is okay in placement but does not blend well with the signature. There is no flow.
