Holy crap. it's Anders! I was wondering why i have not seen you around lately. Ya I was thinking the same on the front block, too much going on. There is definitely room on the back one though. I will stick to a number on the front one. I am using the sentinel painted by automaton as a reference for how to make it look right.
@Uberdark: I am not sure how aliengod does his oxidation, haha. Also I will check out graffiti writer. I was thinking that it would be cool if I can find or create a nice design of Mongo's name using graffiti.
@Ritual: The mini is from Dark Age Games and the mini is Mongo
EDIT: One more thing. Does the color on his neck look too intense?
