The render kinda sucks, which might be the main factor that the sig is bland. The focal needs to be blended to the background more, and the text is kinda bleh...
I would have blended the render better with the background, so that it looks like it is coming out of the background. Looks nice though. 7/10
There isn't much done to it. Also, never put your render on lowered opacity. Just a tip. The background is boring as well. There is no sense of a direct focal, and at first I couldn't tell what the render was of.
