Go Tinker!

Mistress of the Stars
Keeper of the spaceways
Bridger of the darkness
You who turns the arming key
You who closes the priming circuit
Grant us breath where is no air
Let us see where is no light
Preserve us from the perils of space
and the violence of the enemy's paw

GIMP 2, about 30 hours. Some self-made custom brushes.
My entry in the 2017 Space-Revived Chromatic contest.
Space Art Contest: Chromatic! *CLOSED FOR JUDGING!
The Chromatic contest is now closed for judging! Many thanks to all of the participants and everyone who advertised the contest, we have had an excellent showing and hopefully everyone enjoyed it!
TobiasRoetsch and myself will now carefully deliberate the final scores by the 13th. No doubt the selection will be close, with impressive works entered into the competition. The prizewinners will be contacted as soon as possible for their prize preferences!
Take a look at the entries from the contest gallery below:
Please don't go by Axel-Astro-Art

My colours of choice are yellow and red.

Many thanks to all who have commented and offered their thoughts during the process. A special nod of recognition goes out to Planetrix and Zulden for their thoughts on a tricky subject, ERA-7 for her massive knowledge of art theory, and - lastly today - conservancy for a well-needed nudge -.o

EDIT: I intend to touch this up for Art Square, but the original will still be in my scrapbook.
