As stated above this addon, MazzleUI is required for this skin package to work, can you post a screenshot of where you placed the files? or something that will tell me exactly why it's not working for you.

Easiest way to solve this is, rather creating a new folder within the Art folder, you can just copy and paste the files in the package (depending on which theme you like) and drop them directly in MazzlUI art folder. When asked to overwrite, say yes to all.

I'm guessing that you may have mistakenly put the files in the new folder that you created within the MazzleUI/Arts folder? the reason why I suggested creating a subfolder was to keep Mazzle's original arts so that the next time you want to revert back to Mazzle's arts, you can pull it out from that subfolder and overwrite my files.

I was asked to not to release any different skins until whenever the option to pick themes become available in MazzleUI. I also think that it is a good idea as well. So this first one and the last one will be the only available to public download.

If you check my thread in Mazzle forum, you can however check up on any new themes I have made.

Currently, other than the one available to download, I've also completed a nightelf theme, undead theme is next on schedule.
Hehe, I figured out that by listing this package in Mazzle download section, people would figured out automatically that this requires MazzleUI to works. (Or you can even use DART to work as well or any other GUI addon that allows you to do the same thing, but just more work to be done by yourself).
