Awesome work! For the future, making a resource pack is easy. If you want, you can just start with a template (pick any resource pack you've ever downloaded), then just make the folders as they exist in the GT assets... pretty much what you've done. The only extra step is to edit the file at the top of your resource pack folder (any text editor will do) and change the name.
Thanks for the advice. I have not played in the GT6, but if people will like the texture, I'll draw them to the next version. It helps to distract from the basic work, but my eyes are tired .
