Mesh is good.

Feet vary alot, believe me, as I've had some strange responses to my models of feet but the one thing that needs doing right now is as NeoStrider said curl the toes inwards. Doing this will also reduce the space between each toe, which Redmer has pointed out too

Again, the amount of curling will depend on the references you have, I used my wifes as reference, she has pretty straight toes compared to alot of others Ive seen, but the little toe is the one that curls mostly.

Cheers
