Meh I don't really like the first one, I think the second one is pretty cool looking (Brutes FTW) and I really like the last one. THe colors work well with each other and the way the guys holding the SMGs looks awesome too. Nice job!
The Third one looks like the best. I don't really like the rocket one or the brute. Oh and BTW did you know you put "Lawnchair" for the title? Like a chair in the lawn?
