More Intro to Acting work! Hiding your frustration, I'm FINE

In these progression shots, I picked some dialogue that sounded niced and stressed and halting, with the character shutting it all down and just saying "I'm fine" (leave me alone/you can;t help/gotta keep up happy face). This is all work in progress, but I may or may not finish this one. there is some thinking to work out here to get MORE specific with his mental state, and some reposing and timing needs to happen. Curious your thoughts!
