I have files of my characters that contains 504 images, however it is inaccurate because some images or characters are repeated, so I think I have very much over 400 (I will be putting most of them on TH and I already have over 300 😭)
Edit: Including my Warrior Cat OC’s that are Co-owned and my Blob-Bird OC’s (Bird Mochi OC’s that share a universe with my friend’s mochi birds) I definitely have over 500 lol
