In case you're wondering about the low score for a nice looking tile...

There are two major problems with this tile. The first is the big black border line all the way down the LHS - it's going to make it tough to blend smoothly.

The other problem is that you used a photo. I personally don't have a big problem with that (unless of course you've used someone else's copyrighted photo), but with the exceptions of the specific photomanipulation quilts (er, well quilt), people around here tend to score photos badly even if they have been fiddled with.
