Amazing, just amazing sig. I mean most of the times problems I see is having a bg and bla bla, but man! You got it down to par, I can't rate it lol, words won't work.
1st one is sick, the eyes on the dragon are a real "eye" catcher, love the colours. 2nd one, i really dont know what to say baout it, its mainly an ad sig so i dont think i can comment eh.
decent sig, Ive never really liked the height longer than the length but its pretty cool. simple yet good. 6.8/10.
love all the renders in it, its the first one ive seen where more then one render doesnt make the sig look cluttered, love the brushing and the effect it adds 9/10
