When Lesson Zero first aired, I promised on an Equestria Daily discussion post that I would draw therapist-Twilight, and though it took me several weeks (if indeed not months; I'm having trouble remembering at this point) I did eventually get around to it! I have always been of the opinion that Twilight looks quite good in glasses, wouldn't you agree? She really should wear them more often, and I do feel the manestyle suits her quite nicely as well.
Sadface? Ah, not that practicing is a bad thing in and of itself, of course, it's just that I'd rather it was more in regards to something like drawing or golfing as opposed to treating one's physical ailments, if you know what I mean!
