OK, having owned the set for a while now I'll sum up my thoughts on them. No pics unfortunately, but anyway.
Megaempress herself is definitely the highlight of the set. She looks really, really good, and IMO the mold looks far better in these colours than in Pyra Magna's "Coral and toothpaste" combination. She's really expressive, with the "railgun" being surprisingly emotive and versatile. It can flip up over her shoulder, under her arm ala Armada Megatron, form a scorpion tail... The silver paint is gorgeous but I wish there was more of it, as the "silver" plastic isn't the best. My only other complaint is that due to being a straight redeco of Pyra Magna, she's quite obviously just a silver fire engine. I may have to make some Shapeways upgrades to make her ladder assembly look more like a railgun.
Lunaclub and Moonheart (or Windburn and Pulsewave as I have renamed them) are the best iterations of the helicopter mold I've handled. The HFG ports have been thickened so no more cracking! Hooray! On top of that, the colours actually work pretty well in that late 80s way, with Moonheart probably being my favourite of the two. Also, the swords can peg onto their tail assemblies via the slots for vehicle mode.
Flowspade (aka Motorhead) is a lot of fun. She's a very nice shade of lilac and she has a definite ninja look about her (maybe she's a student at the same assassin's temple as Nightbird?). Her bow weapon is pretty puny, mind you, even for a bow.
Trickdiamond (aka Razequeen) is probably the weakest of the team but is still a good toy. The black and yellow reminds me a smidge of a wasp, which is cool. Her weapon isn't the best, but I think it works better as one of those Aztec club things (someone remind me what they're called again...) than as a shield. I do like her a lot more than I thought I would, though; from photos the headsculpt looked dreadful but in person it's adorable.
The combined mode is great. The colours really work, and every combination order works well. The sword is fantastic, and that headsculpt is just to die for. The feet could have done with forwards/backwards movement but overall they're good (the rotation where they join the leg helps. The hands kinda suck though, they're a bit tiny and the port really should have been in the hand itself rather than in the wrist.
Overall, I'd say this is a fantastic set. Almost no QC issues short of a few ever so slightly loose ports (very easily fixed), great presentation, especially in combined mode (which could easily have been a clusterhug with all those colours), a tonne of personality and some of the best feeling versions of the much-abused CW/UW molds. Unless you already have Victorion and really don't want to own the same molds twice there's no reason to not recommend the set.
