Whilst yours are more 'realistic', at the current resolution and the way they textures are stretched it's not an improvement, it's a downgrade. But I appreciate the effort.

Agreed with @Sebianoti, although I don't think it's quite a downgrade. You're going to need to make a longer version of that texture in Photoshop, and then squeeze the texture. What you'll get then is a texture that is (hopefully) scaled correctly without much stretching or condensing.

When I made the Patriot lights I had to REALLY stretch the width of the circle to make it round on the actual model. Took some playing around.
