ISO: Reference!

I'm looking for a reference of this bab here; 

I would like a double sided reference and i'm willing to pay extra, however if you can only do one side please let me know and the side i'd like is the one with the skull marking.

Custom or free lineart is fine as long as credit's are displayed.

This is a boy so stallion or unisex lines please!

PM or post your examples and prices.

THIS IS NOT FIRST COME FIRST SERVE

Thank youu! ♥
