I think the colors are great. The things I would have changed about it? Well maybe reposition a couple of cuts, Torrie's head is only half there in the top right. The watermark is also there from the person who uploaded them, getting that out would have helped a bit. The left pic looks like you've taken the eraser and just chopped half the pic off to fit in, maybe some blending to go there. The main cut is failry simple, maybe could have gone another effect. Text is average.
But hey, I'm not picking on it. I personally really like it. 7.5/10. Again, the colors really work.
