Sci-fi Themed Art Collection

I have been creating things that relate to Science Fiction. Initially it was mostly about UFOs and Aliens. It's art that is fun to do, since it's more fantasy related. I've had viewers of this style of art call some content as whimsical, but it can be quite subtle or right away it shows that type of 'humour' in the work. I am a colourist, expressionist, and try other things, like minimalism.
