NICEEEE I really like the first one, great depth and good effects... Second is still good but I've never been a fan of vert sigs
I like the halo one because everything is black and white and that orange colour gives it a great effect :]
I'd like to see them in color if you have. I think that prince of Persia one has a lot of potential with a color version. The halo one is nice as it is though.
