In a different timeline - 90s Turtles meet Batman 89
I was a big fan of Tim Burton's Batman movie as a kid, and I also loved that old Turtle movie.
When I found out that they met in the comics, it was clear that I need to make an illustration of them!
I was going to paint an epic fight scene but I ended up with a very simple one - the Turtles are just hanging out with the Dark Knight and having a pizza! :D
I built a simple 3d scene based on a super quick sketch in Maya and painted over my render in Photoshop.
