Noice.
I like the edits you did on Kitana, especially the hair. However, the colour on the lower part of her costume looks too uniform (ie: not enough variation of blue) especially when you compare it to the diff shades of blue in the rest of the costume.
But you've fallen into the same trap as the MK team did back in MK3 by having the slicing make no sense - Kitana has sliced Mileena in the middle but Mileena's hand is still there floating in mid-air. The rest of the dismemberment is cool, esp having the top half of Mileena's head missing ala Kill Bill.
The blood isn't too bad, although (just like Kitana's costume) its too much just one shade of bright red and is sometimes too thick (like the blood on Kitana's fan). Also, I don't get why there's so much blood floating around like mist. You've gone overboard with it.
Watch out for the lifebars - the blue is supposed to be draining from the other side, towards Kitana's name. Look
here if you're not sure what I mean. I'd also suggest finding their names on Mk Warehouse and using them instead of the odd, shrunk looking ones you've got there.
Keep up the good work.
