I created my own vector version of Harley Quinn and Poison Ivy kissing by tracing over a panel originally drawn by Shae Beagle & Roberto Poggi from Harley Quinn: The Animated Series: Legion of Bats! #2. I made some alterations to the girls, added some new effects, and labeled this recreation "Harlivy." I've included a side-by-side image for easier comparison.
