This makes me think of Griffin and Sabine (a book series that everyone should read, hell yeah).
Which makes me think of asking this question. Do you think you might be interesting in making stationary? I'm sorry, I really like how colorful and playful your work is and I instantly thought "wow, I'd really like to have a pile of stationary with cute goldfish people on them".
Don't you just hate it when you do a picture.. then someone comes along and does the same idea but 10 times better than you?! I did a goldfish mermaid a while back.. but yours is so much cuter than mine!
