Of course you will, it just takes a lot of drive and motivation but you seem to have plenty of it as long as you focus. Something to keep in mind from viewing all of your concepts (save for “The Inhabitant”) is that they seem to lack contrast, many of the colors are all the same light shade with little variation between light and dark, while this achieves a watercolory dreamlike effect, it also muddies the image and evokes the wrong feelings for something “space opera” I think. Though this could just be a side effect of the way you paint (everyone styles are so vastly different) a deep and rich contrast brings out details, and it’s the details that help bring sci-fi to life.
I really hope you get this done, I too am a bit of alate bird, but I just found your forums yesterday
