I am board and I was wanting to start a forum where U can post some tips to help people render. My tip, when U are cuting take your magic wand select your pic then feather around 1 px
Right... Anyway magic wand is choppy... zoom in as far as you can and use the polygonal tool and cut around it
Make it transparent Filter > Extract > Brush size to 10... Go over some rough bits with the History Brush and use the Magic Wand tool it helps.
