Skin Size: 128x64
I have recently gotten into HD skinning, and here is my first one!
Nitrome's (a British Flash Game company) Favicon and mascot, Cuboy:
The base image I used:

Please do not just click "Save" on the image of the skin, then I will not get any XP gained from downloads. If you do just save the image, at least give a diamond. To download the skin's image file, click the MCEdit schematic download button. Thank You.

Any feedback is appreciated.

Instructions on how to equip:
A. Use some sort of HD skin mod, which should have it's own instructions
B. (If you have some sort of mode, such as MCPatcher, that allows for HD Texture packs) Create a copy of your favorite texture pack. Then, edit it, and replace the char.png file with this skin. Now, whenever you play offline mode, and use the texture pack copy, you'll have it. Mods are required for it to work on Online Mode or SMP.
