Nice job mounting. I'm not sure how often 'Little Stars' blooms (I got one recently) but it looks to me like a nice division. If you are ever in doubt add a couple more bulbs to your count before dividing. I usually don't go less than 4 mostly 5-6 or more depending on the size of the Mother plant. I figure on giving the plant enough strength to get it's new roots going.
Nice piece of driftwood you found
I love mounting on driftwood. I can water often an not worry since it drys out overnight
