Texture artifacts and normal map issues

I've got some weird discoloration/artifacts on one of my models. It only has a 1024x1024 diffuse texture atm. Using DXT1 compression.

diffuse (still needs some work)

I'm also trying to bake a normal map from a high poly in Xnormal but I'm getting artifacts on the edges. I'm using a cage but it doesn't seem to do much.

Any help would be appreciated.

    Try to make the UV map with exclusively straight lines, and if you have artifacts, stay away from any DXT type, compression will do that.

    Alright, I changed the compression to BGR888 and it's fixed now, however it did increase the size from 600kb to 4mb. I'll probably make it 512x512 though, which should help a bit.

    I don't think I'll use normal maps on this model, but I'm not sure if it's just because of the curved lines. I'll try it again when I make my next model (today or tomorrow probably) and see if I can get it to work properly.

    Does the UV unwrap look good to you, despite the non-straight lines? I'm relatively new to all this so I'm not sure if I'm doing everything right.

    Not using compression will do that, as opposed to the DXT types; so you see the pros and cons of both here.

    If it works, it's good enough in my book; though you did seem to have normal map issues.
