I worked on a PBR texture showcase about a month ago in beta studio, and I think it would be nice to post it here so I can get excited when PBR textures are released so I can give everyone a chance to play it. I took pictures of it in beta studio:
All in all it is not bad. However, I do think you should try and make it flow better. I know that seams are a pretty dificult thing to make perfect but it takes time and practice.
For example;
That spot right there does not flow very well and is not very realistic. You should watch out for the realism in your textures and I am sure you will be able to make some pretty cool stuff if you practice more!
Yea that would probably work but another thing you need to be careful with when you are texturing things is the stretching. Texture stretching can totally kill the whole vibe of the game because it looks really choppy.
