I have 4 frames that I want to fill with art since I don't have any actual pictures that size.

I was thinking for the two small cat ones I could put in a picture of Kat and Peppermint Swirl since Peppermint was my first OC, and Kat is kind of like my Personna.
For the big white one I was thinking maybe I could draw a picture of my friends and put it in there, but I'm not sure what to do for the Disney one.

Any suggestions/ideas for any of the frames?
