I loved Pacific Rim. So much, in fact, that I'm starting a new project! As LAF tends to be a great source of inspiration, I'm turning to you for help. Pacific Rim has a very distinct style, and I'm not looking to duplicate it 1:1. For me it's more important to capture the feel, not to create a full replication.
For the Jaegers I'll go with Reaper's CAV and Battletech, setting the size of the Jaegers at around 50mm. Like this:



The Kaiju are more problematic. I'll probably get a few of the Clix ones:


The rest are posing a challenge. They'd need to be around 50mm, and not too recognizable. This rules out most of the traditional fantasy and Cthulhu monster stock. Reaper's Stone Elemental can probably be painted up nicely enough (and as I said, I'm definitely no purist):

And this Hordes monster looks to be perfect:

Any suggestions? 50mm or so, suitably alien, bipedal-ish, aquatic look a bonus but not required.
