Came back from school now, it was alright

Anyways, since I got Art Class this year (Last year I didn't because I wasn't picked to go there or something...) they gave us a folder, I guess it was pur art folder, and our Art teacher let us decorate it!!!! ^^

So I drew Azul, but I don't know what else to put, I may put in few Apocalyptic Wastelands characters but any suggestions to put on here, and if you want your OC there, I would be happy to put them on ^^

I will soon color it tho, but now.I'm sketching it out :)
