Let me just tell you, I'm going to be blunt. So if I hurt your feelings, get over it.
Your sigs are simple and linear.
Start trying to add more aspects than, "BG","Render","Text". Also, I'd recoomend losing the text for a bit until you get good at it. You need to know where to place it, and where it's going to look best.
You need to work on making something that isn't just a regular texture background. Get inspired, make something unique. You're going to get no where with these kinds of tags.
