I've left the roof as it is and I've decided to release the skin now.
@beefyman666 - you can add the 'torn' bits to the roof if you want, I cant be bothered
Attached in 2048 and 1024 versions. I'll upload to LFSW in a second.
EDIT: If you use the 2048 version be sure to rename it to FZR_Sprite_1024 or other players won't be able to see it.
