Ok first of all post pictures of the skin ingame, don't post pictures of the skin in photoshop, because then people can rip your skin like that if it's worth anything. Well i actually did rip your skin to show it ingame. The spots you missed with flesh, makes it look bad. The weapon looks like it was to tried to be alphaed out or just made white.
Keep trying when skinning change everything you can! cover the whole thing, go above and beyone!
heres it ingame |
