Yes, the hands are transparent (it´s a ghost). The cyan is "oversaturated" to make an spectral light. (I hope I have done it well) .Thanks for the blueish tealish grey.  The original bg was in grey pattern, ´cause that the aa is grey. When I changed the bg colours the grey line seems not bad to me... But you´re right: it´s better as you say. :)

Yeah, keeping in mind that I tend to do AA to death, I'd agree with Lawrence here. Change the gray to something that'll blend with the background, and make this baby smooth.

I quite like it as is, though. The cyan is a bit oversaturated for me, but that's just personal taste, I guess. Great ditehring on the BG.

I'd recommend changing the grey aa to a blueish tealish grey so that it blends better with the background.
I like the background, and that cool turquoise pattern reminds me of LoZ: Wind Waker. Are his hands transparent? They look quite cool.

Very nice. I agree it seems like a bit too much aa. I do love the markings on his clothes.

The grey "aura" makes less AA betwwen the black robes and the background. If I had paint without the line (if you see closer you can see that isn´t a continuous line) the alias was a lot , but thanks for your critic....err... Where do you live?(...mmm...yes...ok... I have a gun and I knows how use it...)

Pretty cool. Don't like the gray aura around him though. Less aa I would say.
