That's a great piece of hard work. Congratulations on finishing it! Haha. It looks like some kind of sci-fi art to me. :) I think you can also tweak it a bit more as a digital art and make prints of it. I'm pretty sure it will turn out awesome too.

And congratulations on getting upvoted by @ocd and @curie! That's one thing I've yet to experience here on Steemit. Usually it's either I get one or the other. Lol.
