Kinda predictable, but some ace visualisations.
I liked his nervous twitches and all the expressions. It's a repetitive and predictable joke, but the visualisations made me smile.
After flashing, he seemed to get a tiny bit calmer, which disappointed me. I was hoping it'd get even more ridiculous. Maybe the ending could have been him having a heart attack?
Though you're obviously new to flash and have stuff to learn, you've got a great grasp on poses and histrionic expressions. I look forward to more from you!
