Yes it is that perfect! Ok maybe not perfect but it's really nice. I don't understand what the light dot is doing there. The text looks fine to me (except for the KD which is odly places, I would just drop it), I'm not an expert in it (not at all) so ye .
Too much green for me. Try having at least one other color in it. Text kills the signature as well so work on that.
The effects stop too abruptly on the edges. Needs to be blended a little better, maybe add more color.
