Ooh. Nicely done. Jeanette really would make a great science officer aboard a Starfleet vessel.
It's funny, though, y'know?; ever notice how nobody in character in Star Trek effectively wore any glasses? I guess Starfleet Medical technology is so advanced in the 24th century, that "poor vision" has been pretty much cured. One of the few exceptions was Geordi, who wore a "VISOR" device, which was because without it, he was completely blind anyway.
Seriously though, pretty cool drawing. You've got some great dynamics in Jeanette's expression here.
