A while back I posted a thread on my Elemental Udyr skin concept on the official forums, found here: http://www.leagueoflegends.com/board/showthread.php?t=129066
Since then I got a hold of the tools necessary to make my own skins and got to work. Ideally it would be a remodel, but I don't have those tools, so this will have to suffice. It could use some work still (the icons for changing stances being too big, for example), but I'm pretty pleased with how it turned out. Once I get some more time I might go in and fix some things or change things based on suggestions.
The elements are Fire = Phoenix, Earth/Plant = Bear, Water = Turtle, and Tiger = Wind.
Note: After making this skin I came to find out that Lucifer of Pride had already made something similar here on Leaguecraft. I did not intentionally copy (I think my original concept art was posted before his skin, but that's not important) as I wasn't aware of his skin while making this. I figured I'd post it up here anyways despite his already being here.
