This is my Delta Squad member and I think I did a good job. I used a skin program (MCSkinEdit) and if that is frowned upon I'm sorry. But it's the look that counts right?
Anyways I thought it was cool and used it for quite a bit.
Again. Be gentle. First uploaded skin
Also for an unknown reason, the previewer isn't working for me. So if you would like to save your previous skin wherever and then use this you could always just revert is so, yeah.
