I find this skin very boring. Where's your originality? It's just a box pasted from another image file. Really, if you make something and want to publish it, be sure that the skin is good enough to hold critique.
Lol, never heard of lol-skins?
This indeed is a lol-skin for sure. The only thing I'd like to do with it is this:

Don't copy this as a skin, lol.
This makes the skin (box) stay on the ground, instead of hovering in the air, and makes it look more real.
A tip: Put the skin up, use the nickname ''Mortar Launcher'', and then play mortars. If someone is noob enough and doesn't use the map, you can the trick people. Still, those people requires to download the skin aswell.
Still, I won't download it.

I'm not into much o lol-skins ingame, more like watching them. And there's not many in LXa who has Item boxes and health on anyway.
