Very good playing for someone only 2 months in! But I’m not the least bit envious…no no no…not me!
As others pointed out in a previous post, your posture could become an issue.
Here’s my analysis:
-
In order to “pin” or “pinch” your guitar between your right leg and your right arm you are dropping the guitar neck too low.
-
To compensate for the low neck angle, you are dropping your left shoulder. This makes the fretting easier, but at the cost of twisting your spine.
It might be a simple fix - just raise the neck and straighten up your torso.
But if your guitar/body fit is similar to mine, this will destabilize the solid pin/pinch you are getting, and create a new problem - the guitar will not feel secure in your lap, and the neck will want to move around.
In that case, I’d suggest you either experiment with playing seated with a strap, or look into guitar lifts that rest on your leg (someone recently suggested rolling up a towel and putting it between the guitar and your right leg - maybe I can find and link)
EDIT: Found it… EDIT 2: towel or lift goes on LEFT leg, not right
