YAY! Finally i've drawn a quick but full-body reference of Nitro! :3
(OMG HIM LOOKS AMAZING, HE'S SO COOL... CAN I TOUCH HIM?! YES?
It looks pretty empty, i've drawn it quickly so it's not a detailed sheet, when i'll find some more freetime maybe i'll make something better! Even it there's not much left unseen of him o3o
