Things for you to look up/try later on:
1. Blend in the render with the background.
2. Pick a better background. Sometimes you can make your own background from scratch, or use a render and use tools for making them.
3. The text isn't suppose to be seen as one of the first things you see. Make it MUCH smaller, and pick a good color. Blue doesn't go with the signature at all, nor the stroke.
Also, wrong forum.
