Good choice. Plenty to go on, so high quality images aren't gonna be a problem. If you've downloaded AK's All-in-one pack and the handful I've made, duplicates shouldn't be an issue.
I'm continuing work on Nereids. Then on to Hybrids, Dragonkin annnnd... Centaurs I guess hahaa. There's certainly no shortage of images for them!
Look forward to your first pack :)
