Hi,
i like your mix, has a good balanced overall.
Also to put the harp on the left and the guitar on the right was a good decision, because it is played like a second guitar.
If that would be a harp instrumental then it would be in the center.
Only the guitar on the right could have a bit less low mids, but on smaller speakers none will hear that.
And i agree the side stick is really a bit too loud, but in mixing there is no right or wrong, if you like it that way then it is right and perfect.
