Wow I really like the smudging effect. Though try adding some sort of back-lit effect to bring out the focal more. I like the color of the border. It looks like they threw a smoke grenade or something. It's really well done. :3
I really like the colors on the tag. The smoke it really good; but as Cody said it looks kinda flat. Maybe add something behind them to bring them out some more.
Props for being like the only tag today xD Those manga coloring don't really need much criticism. Well, smudging is very nice. I'm liking the color as well, but different shades to put in will make it more eye pleasing. The light source isn't too bad, but if you moved it behind the two Master Chiefs, I think it would look tons better. BLUR MOTHER****ER BLUR. Add some dimension. But some **** on the bg, blur it out so it looks like they didn't come out of thin air :] Very nice smudging actually. That smudge setting has potential, work on that.
