I wasn't satisfied with the new Night Elf druid forms when they came out, and I'm afraid they never grew on me, so I made some of my own!
These are primarily just recolored to make them more consistent with their respective hair colors, although I did change a few things that bugged me other than the colors (i.e. the studded leather cuffs the cats wear was not Night Elfy enough for me, plus it was shared with the Tauren cats). I also wanted there to be a "generic" color that was close to the originals, which you can use with a simple file renaming (instructions in the readme included in the .rar file to be linked).
Right now, these are really easy to install, you just need to plop the patch-A.MPQ folder (included in the previously linked .rar file) into the WoW data directory. Delete patch-A.MPQ folder to uninstall. This was tested in patch 4.0.1 and 4.0.1a
