So, the minor earth pony character Snowdrift from my story "First"?
Turns out someone by the username of Jenetikitty on deviantArt (http://jenetikitty.deviantart.com/) has an alicorn character also named Snowdrift!
Interestingly, the characters are quite different visually. The design of Jenetikitty's Snowdrift really caught my attention and I thought that the contrast of putting these two together would be great, so with Jenetikitty's permission, I did.
Everything done in Paint Tool SAI, without needing to fall back into Photoshop CS5 for anything (which kind of surprised me, since I'm still just warming up in SAI - this is only my second ever serious finished picture using it).
No, I don't know what's going on in this scene. Feel free to supply your own story if you have to, or not, if you're not that obsessive-compulsive.
