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.
*Sigh* I am not happy with this Gothitelle. Then again, this is only my first try doing it. Reshiram/Zekrom will be done as well as Umbreon I'm just so unhappy with this one pokemon.
Anyway, this took me only 6 minutes and 34 seconds. Don't scream when you see it.
EDIT: The Shiny Umbreon took me 4 minutes. I cried when I saw it.
Gothitelle looks pretty good aside from the head spikes, they feel out of proportion. I suggest Drifloon, who is imo among the quickest to draw on paper.
