Well Pinkie thats one way you can fly. You could have tied those things in a safer place of course.
I don't know why I like drawing Pinkie with balloons in clouds. Its just fun.
I also realize the clouds look horrible, I suck at drawing them.
After looking at this long enough, the only thing I can think Pinkie is saying right now is "I love you clouds!!"
Completion time: 2.5-3 hours. Mostly getting the pose oddly.
