I really like how you drew Twilight's yes in panel three and her eyelashes in panel 4. The last panel is all sorts of amazing, Pinkie's pose is very powerful, the way you laid out the fortunes in mid air and the angle of lighting, cool to the 100th power!
"magical mixture that predicts future" if it wasn't equestria i would say "yeah sure" but i still find a program that analyzes the surroundnings and behavior of the ponies is more possible since Twi wanted to fix the machine in the first place and i doubt she could fix an unknown mixture predicting future without Zecora, perhaps why would she want to bring tools instead of you know alchemy and magic stuff? Why would she even need to bring such things anyway... she could've easly moved every screw of the machine by magic and she didn't bring any new parts. Wait just a second, page 4 panel 4, the place where you get your paper is in front of the machine while Pinkie is doing something with it's back.
I don't know why, but the glow off of the floating slips makes the last panel seem a lot more intense to me. But I'm weird, so it is probably just me I love reading these. I get so excited when I see that there is a new one!
The fortunes were self-fulfilling. In that the act of reading them and knowing about them will make them come true. See:
AJ, who craved fritters after getting the thought in her head. Pinkie, who teared up at the thought of crying. Twilight, who thought the machine was broken and left, leaving her friends free to betray her. Then the fortunes that Pinkie and AJ were mourning over predicted what would happen due to them being consumed by obsession with the machine and worry about the future.
