XM Luke is great, Fett is a bit too animated, and Maul is very fragile. Darth Vader from the trio looks quite bad, the best being kid Ani, which is kinda crazy, you'd think Vader himself would be the best, but in fact is the worst of them all. From what I know Iron Studios only made a couple Star Wars statues in larger scale: Darth Vader (the best Vader statue so far) and Yoda (the base is great, Yoda himself is kinda meh).
Both these companies need to understand that Star Wars collectors (as well as Terminator, Predator, Aliens etc. collectors) are more picky regarding accuracy and character resemblance compared to comic collectors. Personally I'd like to see a 1/4 OT Stormtrooper made by these companies, but only if he doesn't look like coming from an animated show or too inaccurate.
