I was unsure about submit something so "unfinished" like this, but for some reason I like it the way it is. I don't know if I'm wrong, but well... I probably submit a more polished version later.
Anyways, if someone have time, let me know if is ok submit this kind of stuff or if it's better submit only very finish work, because I'm pretty new on Artstation, so I'll apreciate any advice :)
