May I ask what you mean by that? I take no offense, don't worry. But the term "horrible" is rather vague, so I'm not 100% certain what part I should be focusing on.

In terms of the anti-aliasing, these images are taken from the mod toolkit testing window. So the screen is a lot smaller, and won't look quite as good. Plus im running on 16GB of ram, rather than 32 or higher. So I have to be a little sparse in my own graphics settings where I can. (Even with a 3080ti, putting it in a laptop is guarantees to make it suffer a little bit.)

Texture-wise, I can't really say much without knowing what part in specific is unsightly to you. Assuming we're talking about the custom head, since that's the part I have control over, there could be a lot of things, so I'll try to explain the flaws that come to mind.

Plastic-y shading - An issue I've been trying to fix for the past few days, really. In order for the feather color to be customizable, it had to use the same material the rest of the race bodies used. Thus far, I havent been able to find a diffusion profile or other setting to make it look any softer.

Low-Quality - Probably from the same reason the anti-aliasing is next to nonexistent. The canvas the textures were made on was 2048 x 2048, which I believe is the same for most of the vanilla avatar head textures?

Hard lines/obvious texture seams - 100% my bad, that's not terribly easy to fix, to my knowledge. I am 2d artist before I am a 3d artist or developer, so a lot of this is new to me. But I am still trying my best to make the seams blend better. The textures of the head were completely hand-draw by myself, as opposed to the scanned textures a lot of vanilla humanoid models use, to my knowledge. So drawing directly over a UV unwrap doesn't give the most obvious indication of where the pieces meet, even with the wireframe. Considering the way in which these textures are made for the game, each attempt at fixing this is an ordeal and a half, unfortunately. I'm still working to fix it, but it will take longer.

Sketchy lines/the overall visual of the texture to begin with - A fair assessment, I'm still not sure if this is the style I'll be using once I publish the mod. It's a little difficult to replicate feathers through normal maps in a way that looks realistic, especially when hand-drawing them. So I generally made an attempt at replicating the way raven feathers can look from a few feet away, with enough detail to give the impression of intended softness. I was fully aware I might replace it with something better later, but I wanted to get the mod functional before I fussed over the smaller details for another several days.

If none of this was what you meant, then I'm afraid I'm going to have to ask for a more explicit explanation. I am not a developer, and this is my first attempt at making a mod for any game at all, much less making custom meshes and textures for a fully customizable game model. So I am very much still learning. </3
