Creative concept... Interesting execution. I think the 'Night Elf -> Satyr' concept is pretty solid (it's fairly well-established that Satyrs are like dark/demonic mirrors/foils to the Night Elves, and I've definitely seen factions that take that to the extreme). I rather like the one truly custom entry, the Watcher who can morph into a lone Panther.
That being said, the modifications are limited. You appear to have used basically the same Satyr face across all the different units, and while I know your options are limited it's still kinda hard to get into. I'm also seeing a lot of weird purple streaks around the ears of units like the Archer & the KotG & the PotM; what's up with that? Finally, I'm really confused by the weird leafy-stone-construct versions of all the animals & the Dryad/KotG; don't get me wrong I love me some constructs, and the wrapping itself is good, but what are we saying here? Do Satyrs ride nature-constructs?
