Have you even started on the actual map yet? I click on this thread because it is obviously in the "WIP Maps" section, but instead of finding an unfinished map I find an unfinished texture pack. If you have some screenshots or information on the actual map itself then please, post them. Otherwise I'd recommend creating a thread in the "WIP Resource Pack" section, were you can get more feedback on your models and textures.
How did you do the custom models for the entities?
I actually didn't use entity models, since that isn't possible yet. I used black models for the heads and armor for skeletons. Whats neat is that i can make them bigger by using wither skeletons to make you seem smaller.
