hiya!! you've done 5 drawings for the orphanage, meaning you've got your first character claim!! with this claim you can either:

a) trade it in to adopt any character without doing the wta
b) trade it in for art of one of your characters
c) trade it in to design any of the waiting for redesign characters in the orphanage, and once your redesign is approved your claim will split into 3 claims that can only be traded in for a and/or b!

of course, if you'd like to think for a while, the claim does not expire! use it whenever it suits you!
