Awesome critiques, guys! So what's I've gathered so far is that the models need more definition (clothing or muscles, where applicable), the textures likely need to be redone altogether (I figure it's easier to redo them than fix them at this point), the speed of the death animations needs to be modified, the walking animations look jerky and weird, and there needs to be something to fill the silence in the background. Did I miss anything?
I think what I might do is make a few different but interchangeable base models (the Kern should be fairly slim, while the Savage should be burly), with a few modifications here and there. I think the Gallowglass definitely needs his own model so he looks as armored as his XML says he is, and I'm actually thinking of completely scrapping the Therian's current model for something more "low fantasy" (like a dude wearing bear skins, rather than an actual werebear). As for the textures, I can hopefully make some high-detail (multi-res) versions of those base models, so the textures will practically make themselves at that point. Anyway, thanks for all the advice! I will definitely be taking it into consideration.
I'm kinda split between two different development philosophies -- "done is better than perfect" (i.e. finish making everything first, then go back and perfect it later), and "it's easier to fix it while you're still working on it" (i.e. fix it as you go along, or else be overwhelmed by having to fix
everything at the end). I'm trying to find a good balance between the two.
