DD, i really like your Commander Krell a lot, the poncho and extra little bits make him a believable fan-fic clone. he obviously is creativly and more important, thoughtfully put together and painted which is becoming a rarity these days when it comes to custom clones.
as far as the galactic marine, the head sculpt looks amazing, definitely one of the best i have seen. as far as the knee pads go, all i can think of is perhaps cutting them off a snowtrooper & pasting them on the marine and doing something like that...but i'm not sure how well that would work. i'm really tired right now so if that sounds dumb just ignore it
the assassin droid is unique looking, at first i wasn't sure if i liked it or not to be honest, but the paint apps drew me in and i find myself liking it a lot now.
i love the blue gonk, gonk's are just plain fun and it's nice to see one pop up again.
the Durge repaint is nice as well, great sprucing up so to speak
as always, i look forward to updates from you, please keep 'em coming
