I think you're capable of a lot better, Andrew.
The main render of Bolt looks out of place. It's kind of just... there. It doesn't blend in with the rest of the sig at all. Try creating an overall tone with the use of colour, even a slight colour scheme could help a lot. The lighting is also well out. On the render, the light is coming from the left of the piece, whereas the lighting on the background is centred around the middle.
Then, it's sort of unbalanced. The sig is so wide, and the main text is on just one side. If the render of Bolt wasn't right down the middle of the sig, that probably wouldn't be too bad, but I'm a sucker for balance when you've got a sig like this.
The subtext doesn't appeal to me, either. Although I just hate Visitor. I think it's a horrific font.
I only say all of this because I know you're capable of a lot better, and know that making some simple changes can help you out a lot. Try thinking about some of the things I mentioned.
