Are you fine with demons? Would be good to know. If not, I'll suggest some other character. Here's my character, Tommy. Some piece with him inflated and floating would be amazing :3

Oh, and congrats for the 777 watchers! Your art deserves it, even more to me :3

JACKPOT ! Congrats for your 777 watcher X3

For my idea, maybe I can suggest my OC Lisette, who is trying inflation, suggest by one of these friends, to feel lighter, but will go wrong and inflated a lot.

Gratz mate ^w^ and thanks for the opportunity for this!

As for the idea... idk maybe her working out? owo

Congratulations on 777 watchers!

If you'd like, I'd love to see you do something with Indy here (ref: https://www.furaffinity.net/view/35858240/ ). He's pretty gullible, so maybe you could do something of him being on the receiving end of a prank where he gets filled up with something and is left to inflate with the source of puffiness just out of his reach (maybe he could be enjoying it a bit, though). I'll leave the rest of the creative liberties to you! Congratulations again on the milestone!

Edit: I just realized I made this comment when the journal was 7 hours old, heh

Congratulations on all the followers! And thank you for the opportunity!
Here's a ref of my OC Brun

As for theme, I think it'd be rad if you could draw her big and pregnant. Thank you!
