I've done some projects like that, although not with as many parts! I think the main disappointment that awaits the author is that within two years or so, the epoxy will turn yellow. These resins are unfortunately not UV-stable, even if kept in a reasonably well-lit area indoors (bookshelf, etc).
There are resins you can use for projects like that if you want them to last, but they're less fun to work with.
