Hey there, lately I've been drawing more and uploading less but I did a color drawing from my latest project. This might give you some idea as to why I don't draw in color:

Not bad. Not bad at all! So, no, I don't see why you don't do more colour :)

That spaceship has a lot of B-17 flying fortress in it. No gun turrets?
Wings remind me of a Rutan Long-EZ.

Cool design!

reminds me of that part from Heavy Metal with all the skeletons on the palne. one of my vaery favorite parts from that movie. and i agree with Oz. i dont see why you dont color more either.

I was trying to edit that drawing using a crappy monitor so it was hard to tell if it'd look better or worse to someone else. But hey, if you two approve that's good enough for me!
Ozone, a B-17 crossed with an EZ was almost exactly what I had in mind when I designed it. Some of my really early sketches did have gun turrets but I thought the looked awkward so I left them off.
Pitface, I liked that part of Heavy Metal a lot too, it totally freaked me out when I first saw it!

The front part of the back wing doesn't seem to be level with the behind part of it.

Also the front part of the front wing seems to be shorter than its behind part of it.

The coloring makes it look rusted and old, that's pretty cool.
