I changed a lot about these two and I'm really happy with the designs! Do note that these kiddoes have new names and I redesigned the cutie marks as well, so their characters changed some. Victor's special talent didn't change though. Valor's cutie mark has a laurel wreath, fun fact about that, it was considered a symbol of triumph in ancient Greece and placed on the heads of victors in Rome as well.

Additional info on Rarity and Rainbow Dash: Rarity dated Applejack for years, in show time it's about from the middle of season one to the end of season 3. After they broke up mutually over different life goals, Rainbow Dash started dating AJ though it didn't last as long because they would fight often. After a large argument which led to them breaking up, Rainbow ran into Rarity who offered her support and understanding. Rarity convinced Rainbow to patch things up with AJ to save their friendship, though they never dated again. Rarity and Rainbow then started spending a lot of time together and found mutual appreciation for their differences and even similarities, finding they were more compatible than they would have ever imagined. After being together for so long, they decided it was time to start a family. Rarity created the kids with a magical spell that she learned from Starlight Glimmer. It took her over a year to get it right and finally create foals from her and Rainbow Dash's essence. More on that spell later ;)
