Well since this is your 3rd I suppose you're still trying things out.
But it looks too crowded this way. Maybe trying to fade some of the pictures to the background and use some effects and colors on this to give it some life and movement. I'm not an expert on this but it's what I would do *giggle*
Don't be afraid to try something new. Take influence from others work and before you know it, you have developed your own style.
Why the heck do you upload a sig when you know on your own that "its horrible", "was made in less than 1 min" or "came out wrong" ... ? Every thread the same excuses.
