For reference, this piece was made a little less than a year before "Crusaders of the Lost Mark".

I’ve been up for a while because I couldn’t sleep, so I decided to draw a little bit to pass time. Some of you were asking about how the CMC (Spike included, 'cause he is a cmc in my headcanon) would look in their teens, so that’s exactly what I did. The CMC teenagers, cutie marks and all! c: I actually drew Sweetie Belle awhile back, and I colored her before scanning the original sketch in. I’ll color the rest as well, though, so don’t worry. o3o Also, if you can't see Scootaloo's cutie mark, it's this: www.signnetwork.com/decals/Dec…But yeah. The Gals are around 15-16, while Spike is around 17-18 (I’ve always seen him as a bit older). The thing about Spike, though, is that he isn’t even a fraction of how big he will get, so the pones better watch out for his growth spurts. xDI’ve got some headcanon on these buggers, but I’m so freakin’ tired, I’ll just do it when I go to post them individually when they’re each colored; kinda like how I did with the Headcanon: Mane 6 image. Until then, feel free to ask any questions you may have, and thanks for stopping by for a look. c:
