It took me a while but here is my 3th fav dragon after Spike and Ember, Smolder! i take her as the big sister/cousin Spikes needs in his life, i like the way they get in contact trough the season, bur of course is a child show, so no shipping fuel for us, still i like the idea. leave all the creepy S($” at side about shipping, one can dream about good things, i hope, in part, to see Spike go trough his crush for Rarity, as much i love it to this day, its just a dream for him and us, and maybe, just maybe Smolder can be one of those who can get closer to Spike.  
Sorry about the low quality of my renders, my PC is “old” and blender 2.49 its obsolete, people working with that stuff knows what i’m talking about.
