I LOVE this one so far. It shows how Sona is filled with agitation. Frustrated with like.. being the support doing all the dirty work and does everything she can to help her ADR.. been there alot of times. Q_Q
I know, I pretty much never feel loose when drawing.
But just experiment, splash colour around, use things apart from the traditional tools, or if you have the tools for digital art just draw semi-randomly on the canvas and see if something comes out of it. The most important thing is to try to have fun! And don't give up or get frustrated if it doesn't work right away, that's pretty much normal (at least for me).
The hardest part for me is usually the beginning, you have the image in your mind, but you just don't know where to start. The most enjoyable is when something is starting to come out from all the lines. Even if it is not much, you get the feeling of satisfaction. The end, when I do the finishing touches, is just annoying. I want to finish as soon as possible, but at the same time I don't want it to feel like something is missing.
