So, I used to do this a lot when I was growing up, like I am sure most of you do. I also do it to get inspiration should I ever need to start work with no prompt or to get limbered up to draw. There are three family younglings that visited me a while ago and they all gave me a different scribble line to start with and then I would draw what I imagine.
Here’s one from the travel illustration set that i did for notebook covers. This has always been my favourite in terms of colours and details. :) Will be uploading the rest soon!
Ichthyornis is an extinct genus of toothed seabird-like ornithuran from the late Cretaceous period of North America. Ichthyornis meaning "fish bird", after its fish-like vertebrae. More like this on: https://www.instagram.com/camilojulianc/
