I was bored so I made a dragon OC

The yellow part on her head, are those spines of is that hair? It's kind of hard to make out. I do like the colors. She has some color to her, but it's not burning my retinas. I'd like to know more, before I say anything beyond that. Could you perhaps explain more about how you see her develop. This may sound crazy, but it's MUCH easier to design a baby dragon if you know what it will look like as an adult. Designing adult dragons is easier than designing baby dragons, because they have more distinct features and you have more creative freedom. Once you have the adult form, you can create the infantile-juvenile state based on that. All you need to do then is refine and rescale and fit it on a Spike-base.

O k she was found by Derpy during a mail mixup she loves derpy and derpy loves her. Dinky doo is a bit jealous of her at first but after some sort of experience they become sisters. She starts attending Ponyville school and meets Spike it turns out they both have some sort of distinct feature shared and after some Twilight style research it turns out their related. Then some awesome adventure happens where there is self discovery, friendship, and sad goodbye or happy staying together endings are both possible depending on what mood your in. Sorry I'd get into more detail but I need to work on my graphic novel if I ever want it finished.
