Well you asked for it.
Here are 3 sets that at the time I made them were very very well liked.


And the famous Crysis set

Just love this set, thats why i bought it

NOTE: With exception of the final one, all of these sets were made by me. I don't believe in trying to claim credits for someone else's work, and decided instead to showcase some of my best sets.

My current set.


Probably one of the more recognizable sets, Cindermomo's. (Linked because it's freakin' big.)

A set I did for the PT a while back.


Richard.


gman80's set.


Something that Monobi's working on (If you choose this one, send him the fee. He deserves it.)

P.S. For really high-quality work that came before Nightmare and probably won't be topped in a long time, see Cevius' work.
