That's pretty much the same for me
I've also noticed that the right hand becomes tired faster. How difficult repertoire are you playing Leah? Do you think being left-handed has hindered your progress?
Not very advanced at all. I'm currently playing Beethoven's opus 49 number 2.
I think it hinders, but I think it's surmountable. There are any other number of things that potentially hinder and there's not a lot I can do about them e.g my current inability to hear how bad [or not] my playing is without recording it and listening back [which may improve, but hasn't done so yet], somebody posted a pdf of Godowsky exercises, which were just physically impossible - if there are advanced pieces that requires the ability to play chords like that I'm outta luck. Many other pieces have physically impossible notes in them too.
So I'm never going to be great at playing the piano, at least not for measures of greatness that are based on what advanced pieces you can play, but although the tension is greater in my right hand it's getting better, so if that is caused by left-handedness it appears to be surmountable.
edit: And for the record, the fact that left-handed pianos are not very common (like similiar quitars), I have come to believe that being left-handed is not that much of a disadvantage.
Yeah, I wasn't serious with that link

I've played guitar and played a "normal" one.
