[NO SPOILERS] A Song of Ice and Fire Bestiary questions and help

Hey there, So a couple months ago I've uploaded some illustrations of the various, more fantastical creatures in the series in a field guide bestiary type thing; http://www.kevincatalan.com/#/beasts-of-ice-and-fire/ It's mainly been a personal project for myself and in honor of one of my favorite series. And maybe to one day be picked up by a publisher for an official book or something ;)

But after doing more and more research I found out there are a lot of really cool and barely mention critters that I would love to take a jab at but wanted to also get suggestions from the community on possible directions to take designs in. For example, the various ape species described from Essos and Sothoryos; what kind of ideas do you guys have about what they could look like or behave for me to illustrate? I'd love to discuss ideas cause I'm sure there are people out there that know a lot more than me and I really wanna do Martin's creatures justice. And of course I'll share my illustrations as I make them!

Hope this post is alright to post here and I just wanted a place to discuss the fauna of this world. Any other resources would be greatly appreciated! (and yeah I have the World of Ice and Fire book. it's been my biggest inspiration.)
