I love the render. Pretty much though all it looks like you did was add a c4d and use a textured eraser and erased some of the sig, then put a lighting effect on it. I learned this in my early days of photoshop, that grunge isn't the way to go. Grunge appeals to a lot of people because it is usually simple and looks very good, but I'd try going more abstract and other styles. Expand your work so you aren't confined to sig making. Grunge doesn't work in life for companies and such. Just my $.02, flame if you want.
A very nice 2nd sig m8,work on the text a bit,well done,cant wait to see what your 100th is like if you can make this on your 2nd
Thanks everyone for all the comments, and cigil, there were no C4D's used =D. I just duplicated the render and used some nice smudging and filters
man, i think this is the best 2nd sig I've ever seen!! i assume you already used photoshop for other things? but yea, change the text, maybe add some photofilters or something and it's perfect! gj man.
