Danielle, I was looking to respond to the “what are the bad habits”. This maybe a little late, but what Sylvia mentioned in her teaching video are things like your posture, no slouching; not placing your feet higher than the base of the harp.
Feet should be planted on the floor, no picking the strings when playing, (referring to when fingers are placed, there should be a pluck, then fingers close in the hand)
Remembering to have elbows comfortably out, instead of having it close to your body, and to keep thumps up…… Things like that. I found Sylvia’s video pretty helpful. Good luck with everything, from one beginner to another.
