Looks great.
A little tip /trick:
I was introduced to using nylon stockings as a tie instead of wires or fishing line. If you cut a piece about 1/2" to 3/4" wide and tie it at the back of the mount, you'll find that the fine mesh of the stockings is almost transparent on the roots and plant, and is soft and gentle.
Because nylon stockings roll when you cut thin widths, that is the reason for cutting the wider band, and you'll find you'll be able to control the material rolling up a bit better and keep it as a band.
I can show you some examples if you like. I used to use fishing line, but by using nylon stockings I need less material, and it holds the plant better.
