At last it has come to this. I said I would sell the last 14 slots for the Periodic Ponies series as YCHs – here is your chance to be immortalised on the periodic table!

Each winner will get a full-body vector of their character (one per element); the pictures will have a 4:5 aspect ratio like the preceding elements and the background will be one colour (default white, but can be changed). At the top-left hand corner will be an element's symbol and atomic number. See 82, Lead, 90, Thorium and 110, Darmstadtium for what to expect, or my other Periodic Ponies pictures from mercury to lawrencium.

Characters may be of any gender and species – including exotic types like lamias and genies – but they will be drawn in the MLP style, which may entail a species conversion. Their design should not be fantastically complicated (a few accessories are OK, dressed-to-the-nines is not); I may simplify some details while working on the YCHs. I will not draw lewds or gory characters, though references submitted may be so.
