I wish I would remember to take more pictures! Aargh!
Anyway, what I do (and have great success with) is sculpting on biters. I use Scotch tape in 3 pieces to "pre-wrap" the nail by using one on each side at an angle ("V" shape) to help pull back those sidewalls and then the third piece straight across the bottome of the non-existent free edge. Butt it right up to what is left of the nail. Pull it pretty tightly to get all that bulging skin on the fingertip out of the way for sculpting. This allows you to put the form in the correct place as if the nail were 'normal'. I then sculpt out the nail bed in a coverage pink forming a new smile line where it would normally be and then butt the free edge right up to the pink. After this is done, I use a clear to cover the whole nail adding a little extra in the apex area and where the pink meets the white for added strength. I also only sculpt shorter rounded free edges on biters for the first few weeks so they can slowly get used to the idea of having nails and don't bust them off the first day. Let them get used to them before you start letting them grow out a little and giving them different shapes.
HTH!
