This little mesh edit removes that ugly misshapen skull from the enchanting worktable. Not all wizards are into necromancy! I was unable to remove the horns though, but to be honest, I don't think they look that bad. This is a quick thing I did for myself, but I'm uploading it here in case someone else may want to use it too.

As this is a mesh edit, it will be compatible with custom retextures, but not with other mods that make changes to the model of the arcane enchanter.

To install, extract the contents of your downloaded file to your "Steam/SteamApps/Common/Skyrim/Data" folder. That's it, no esp required. To uninstall, simply delete the files from your Data folder, and you're good to go. Have fun!
