Mindzeye Studios has only been around for a few years. I would email them your comments about wanting them painted. I emailed them today about pre-ordering two of the hellboy midnight variants and they responded within 20 minutes. From what I have heard (from TOE who has ordered from them before) this line and Hellboy are giving them the opportunity to really break out and make a name for themselves. Because they are a new company and want to attract as many customers as possible, they are probably more likely to pay attention to people's feedback. My two cents.
I love the Boomer statue - not buying any of the GOW pieces, but I thought they did a very nice job on the them. Would agree that a painted version would be extra sweet.
