Spike looks pretty awesome in both forms, so cheerful and friendly yet also a bit proud. Of course he has reason to be, but we hope he's learned to keep that in check. Anyway, you did an excellent job on the cute dragon and the lovely dog version. They're very lively and full of depth and charm. Even Owlowiscious looks to be a little affectionate for Number One. Also, nice job using the nighttime lighting also as a spotlight for Spike and Spike. The shadows are pretty good except that the ladder's falls too evenly across the irregular shapes on the bookshelves. (Though I totally understand it would be a major pain to work out the lighting angles for every edge and book.)

It's a lovely little scene that pays tribute to all forms of assistance that Twilight Sparkles can always rely upon. Thanks for sharing.
