This was my first ever idea for my character, Acidic. This concept had only one piece of traditional art, and I unfortunately have it no longer. So, as a delve into the past, I made this quick sketch.
Acidic has a long history, as she is my main, oldest, and 1st ever oc I made. In this, she was portrayed as this shadowy western dragon that I thought could look cool in armor at some point. But, as time passed, I got into dinosaurs more and more. I wanted a dinosaur character. Sadly, I liked this character too much, and I changed her. (A lot more occurred for her change too. Etc etc.) Now, she is a drake, or a wingless dragon that is part ghost. This was inspired by dragons, horror, and spinosaurs.

If you're curious, Acidic is 5 years old. This concept came to me in 2017.

If you wish to see Acidic and how she has changed since then, these are her newest references...
