Paper crane

Wow, it's been so long since I did fan art... Either way, it's supposed too be Sam and Grace from Maggie Stefvaters book Shiver. It's probably my favorite book series, but it's been a while since I read it so I'm not sure I got everything right Also I bought tracing paper a while ago and this was my first time using it Which means I can sketch out what I want to paint on ordinary paper so I don't ruin the watercolourpaper if I want to do something more detailed Oh, and in real life the background is rainbow coloured

Made in watercolour
