Sketchbook Pro

I made this image in Sketchbook Pro for the iPad, and as you can see I'm still getting used to it. I'm currently making a page for an alphabet book, with the theme "T is for Together", and somehow I've managed to end up with the letter Q. Quadruplets/quintuplets seems to be working for me at the moment and I'm trying to stick to the idea of the quadruplets being kids and still living together. I've tried to keep the image simple through colour and type and reminiscent of a child's alphabet book and while I could have drawn four/five identical quadruplets/quintuplets I wanted to let the audience think a little.
