Eh. I could have done those renders for you. You might want to move the renders over the footprints. That look WeIrD when you have footprints in there. Those renders would look good with some abstract brushes. I am going to guess you are using Photoshop. So go to deviantart and grab some abstract brushes. Just use the search. Then upload them to photoshop and you have some cool brushes. I would reccomend Total Deviance Brushes, I use them alot and they are great. overall I would rate these sigs a 6/10, because you are a newcomer to graphics. If these were your 10+ 11th sigs, it would be more like a 4/10. Keep working! oh yeah. If you have gimp, there are some ok brushes for that, too.
