I tried to decide if I'd prefer this lively picture with just one (and if that, which one?) of the two Fiddle Sisters in shot. Nope, I like it better this way. Plus they can play two parts of the music this way. Sounds great! Thank you.
The left one looks like a giant. Are they twins?
The cutout can be improved. Many tutorials are available online using masks to do a proper cutout in PS. I give you a 4.
