WF13 looks good. Only two things I see that could use some work: The tri-jammer needs to be pushed back towards the dumpsters a little more, it wasn't that close to the semi stack or the jack rabbit stack. And also the flames on the center jump came from the big side only and trailed all the way down to the other side, there were no flames going in the opposite direction. Other than that you're doing a phenomenal job!
