Well OP you're going to need a lot of practice but I think you've got the basics covered, you just need some tweaking. I mean you know how to play the violin, maybe it's your violin that needs a bit of tuning. Keep it up! Also what's with the dimmed room. Creeps me out man, did you do it on purpose so you keep your anonymity

Edit: Just saw your piano videos. Gotta say you actually play the piano pretty decently.
