The sculpting looks good. I wouldn't think of Hyperion being that beefy, but I haven't read any comics for a while so I'm not up to date.
Thanks! As Ajsalium pointed out, he is a Superman equivalent and is typically drawn pretty beefy. Having said that, it looks to me like the picture has flattened him out a bit more than he appears in hand. His arms are pretty gigantic, but I'm not sure his torso is that wide in reality.
Hyperion is typically portraited that beefy. It's a parody of Superman, after all. As far as I know, only the Supreme Power version is realistically proportionated. Some pics...
And regarding weapons for Crossbones, Hasslefree Minis have a nice range of them, that you can find here:

And Reaper Minis also sell some packs. Just type "weapons" in their Figure Finder:

Thanks for the picture assist. And thanks for reminding me that Hasslefree does modern style guns as well as their scifi stuff. I will definitely be getting some guns from them for this sculpt as well as possibly for others.
They both look really nice - Hyperion especially so.
If heads and hands are a problem for you, I'd suggest sculpting the head(s) separately, then you'd be able to attach them when you get one that you feel is up to snuff. As for the hands, they're definitely difficult to sculpt, but fists the size of Hyperion's shouldn't be as tough as a smaller figs.
Definitely keep at it!
Thanks!
I am definitely going to try to do his head separately. I don't want to do his hands separately though. I need to learn to get that down, plus there is a lot of interplay between the hand and forearms that I don't want to leave out. Or try not too, anyway.

Couple of blasts from the past, circa 2007:

Heroclix Jean Grey conversion. Not much sculpting done, as I recall. Just added the leg bands, I think.

Heroclix Dreadnought conversion. Lots of sculpting here. I call him Pharaoh now. This is an unpainted WIP.
I need to dig them out so I can use them as well.
THought I'd throw them up for your perusal since I don't have any appreciable updates on the two sculpts yet. Been pretty busy and a bit sick.
Back at it soon though.
Thanks for looking.
