My pic here from my Haloween free art givaway.
From left to right, top to bottom we have:
 generalguy64's character Fresh as Isabelle from her appearance as a villager skin in smash brothers.
 OrangeMario's Mr. Poloman as a generic Witch
 Skunkman001 as Morrigan from Darkstalkers . . . riding a pink balloon dragon for reasons that are beyond me
 PurpleFox213 as a scuba diver that has inflated their suit with helium
 doonething character Rachel riding a floating magic carpet via balloons
 tmanwade260's Nitro as Pennywise
 ErinRedFen as a generic mad scientist with a balloony death ray (I went with Baron Blade from Sentinels of the Multiverse)
 ArcusMike99 as Mario with a balloon Fireflower
And lastly  Snypor's Pony OC as CoCo bandicoot, with an inflatable bow, and I added in a balloon version of the floating tiki mask.

As always, comments are appreciated.
