hmmm, ur style isn't exactly a style I like I guess... but yea we all have a different taste
like the font u use for your name often doesn't look good.. dunno desn't fit the sig I think, personally I prefer it just black or white, and then maybe with a glow.. keep it simple is the key there.. another thing, u might want to try to stay away from all the filters, start brushing etc..
but I think u did a fine job despite the fact that I don't really like them, others seem to like them so that must be just me, keep it up!
