Lehigh74,
I think you did a fine job, and thank you for the compliments. If you used building foam, it is very strong isn't it? It has probably gotten you thinking about all of the different things you could make with it. It allows for carving, painting, gluing, has a high resistance to compression, and allows for advanced working techniques that result in a different finished look. Once it's painted, it becomes tough as nails, strong, dense, yet extremely lightweight, so if you bang into it, drop it, it can't even harm itself, because it is so lightweight.
I love experimenting with it, and working it with different tooling, and trying new techniques to get more refined end results. It is a joy to work with in my opinion, so much easier than wood, so I use it whenever I can as an appropriate substitute. It also combines well with other materials, but of course, not everything.
I myself, am still learning of all of its capabilities, and that to me, is one of the most enjoyable things in using it to make stuff. So many things to make and try out, it is almost endless.
