This looks beautiful to me - If this is your 1st hand quilting, you do work like a pro already - I sure don't see anything wrong w/it.
Perhaps "rocking the needle" would be easier if you make sure not to have the quilt stretched too tight in the frame. Plus practice will definitely make it easier. Hand quilting is all I ever learned & some of my 1st tries would be something to cry over (just short of being "toe-nail" stitches), but over the years they became easier & more comfortable for me to do.
Have a blessed day & may all your quilts be filled w/love.
