You did a good job with this retexture, adjusting uv's to fit images from pictures isn't easy. Unfortunately I don't grant permission for re-releases of the model or it's assets to be reused in other projects. The unconverted model isn't mine and I promised the artist who made it that it wouldn't be released for public use in this way. Other than the tail it looks like it's just my model with a new texture. This is a great idea but you'll need to use a different model as a base for a public release. You should try using the original enemy model from the game, it'll fit the skeleton perfectly too.
