Okay, so I've expanded the stone tile accents from the original S3&K enough to almost be able to use it as its own texture set. The problem is, this texture sucks. It's really bad when it tiles a lot, and even when it's used alone there's still that big gaping blank spot in the center.
In case you need a reference, this is a sprite sheet of the original LRZ2 texture set. The "stone tiles" are the turquoise stuff that Sonic walks on, as well as the supports which run through the foreground. The image above uses the colors I've picked from the SRB2 palette, if you were wondering.
I can't think about how to fill that open space myself, so I turn to you guys. I know we've got a bunch of pixel artists in the forums, so I'm hoping that you guys will have some ideas as to how to fill that space. I'm mostly looking for something subtle that repeats well. If you've got something that looks good but isn't either of those two, post it anyway. It might fit my needs regardless.
