I love that scene so much! I was thinking of making a gif of it myself, although I probably won't now, especially since I can't draw, mine would've just been a typical gif, yours is much more awesome, great job.
That was an absolutely hilarious scene! Would you believe it that I actually thought to myself "where did he get that" when I first saw it? He either had to summon it out of thin air like the angel sword or just have one lying around. You know what, I don' even care, he's the King of Hell damnit and if he wants a bloody pinwheel then by gum he can have one!
Excellent art work! May I ask how you managed that animation for the rotating wheels?
Thanks !! I did it all on Photoshop with the animation option: it's kind of easy in fact; you create like 3 layers with the pinwheel on different positions and you animate then the whole thing with a high speed. And normally you have a decent gif. I don't know if this is what you wanted to know but I hope it's useful....
