Here's the final product of my second project with the Koi and Cherry Blossoms. The one thing I didn't like was the cracks that appeared in the acrylic, but I think that was me not being careful enough. Not sure if it was temperature that caused it or just holding too tight?
The camera doesn't show all the detail, but here it is.
Changes I would possible would be making a stand for it, or putting the reflective tape on the edges to trap the light inside better.
