I like it. However, I think that the background should be different and that the render should be blended a bit better. I understand of the left side represent Goku and the right side representing the evil Freya but then there's that blurry spot there on the right that I see is a little bit weird. As for the text, maybe if you chose a different font, that will help complement the signature more. The color is good but the font needs more. Still, you are doing alright. Keep on doing what you do best and make the best quality of work and I know that you can do it!
A couple of the staff members came together and have an answer. Right now, your render is placed very well. However, the problem is mainly the background. To one, it is bland, to another is the lack of depth and merging but KHPlanet do agree that the text needs some and that it may benefit better from a different front. That is not to say that this signature is terrible so please do not be discouraged from this critique. KHPlanet still like your work and hopefully, you can show the rest of the members your graphics on our site too. KHPlanet hopes that you continue to improve.
