Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Typically, before artists create an art thread, they prepare at least three pieces of art. Since you've only got one, I'm going to close your thread until you're ready.
To post images, upload them to an image hosting site and use the "image" button, pasting the image URL.
If you have any questions on anything, please feel free to hit me up (or my fellow moderators, elcheeso or RitterCat )
