Firstly, sorry for not relying sooner! ^^ I haven't been that active around here.
And I would love to do an art trade with you! If you're still up for it! Your art is fantastic! For your half I could probably only do the unicorn, as I haven't had much practice drawing other things, I can have a go at the anthropomorphic dragon, but no promises to how it will turn out. XD
And for my part, could you do my OC Spectra Dust - http://i.imgur.com/ffc6Mso.png
If you're still up for the trade, I'll get started on your right away!
