The 'Music Lessons' and 'Rentals' images are now correct. Before they were swapped.

The blue band for 'Rentals' isn't properly aligned with the image.

I understand the 'stutter' comment - I noticed it wasn't smooth scrolling always and I find that when I view using Chrome or FireFox, it's smooth after the images are cached, it's not so smooth on Safari.

Not so keen on the sans-serif menus, and some menu options, particularly on mobile, don't do anything.

Stylistically the site is a mixture of 'Classic' and 'Modern'. I'm not sure that's so good.
