I suggest you just keep trading YM to get familiar ... then you can move to ES or NQ as you see fit.
I don't see anything wrong with starting with YM, that's how I started (to lose money) and I moved to ES ... after switching from YM it may seem that ES moves slower ... as it thicker as apposed to YM.
Good luck.
