Pretty drawing, I like using coloured paper too, sometimes it is helpful and you do not need a lot of different colors. YOur pencil seems to have very busy life, how can you use such a short stump of pencils, or another question, how could you sharpen it?
I've only recently found coloured papers... lol .... I've been sleepwalking or something or just never thought about them, but yes, they are really great to draw with :>
It still is sharpened with the usual sharpener :> but it's nearing its end.... soon i wont be able to sharpen it properly :(
