Rather than chronological order, I'll start with the stuff I'm most proud of, and try to group by theme and style.
Admiral's Duel
I like the idea that a major battle between two fleets might be averted if both admirals are willing to fight it out with each other. So here is an admiral, without armor, with just a sword, and his two bodyguards, in heavy armor and armed to the teeth. The hardest part was making the fleet in the sky stand out - in the first version of this piece, I actually got the comment "your stars are weirdly orderly and grid-aranged". This one's from a story that exists only in my head, for now.
Blood Lake
A spacecraft advanced enough is probably indistinguishable from a living organism, and too large really 'die'. As a corpse rots, so might a crashed spacecraft spill its internal processes. Maybe it may try to repair in some suffering manner, while hiding in fog, making an effort to ward off interference. It'd surely look odd to anyone who doesn't know what it is or what it's doing. I made this one after playing Signalis - hence the red.
Low Pass
I like antimatter drives, a lot. The gold rings are radiator clouds.
I really do like antiamtter torches.
I like swords, too.
Armel
Not much time spent on these, just interesting arrangements without finish, inspired by moments in REKT.
Speaking of REKT, some tokens! I'm actually really happy with these, even if as with most of my 'people' art, they are traced in shape. I never leaned to draw people or faces.
I traced a 3d model I posed myself to get the pose right, but it still turned out a bit flat from perspective and pose. Still pleased with this one, maybe the most complicated proper 'art' piece I made to date.
Most of my art is more 'untextured mechanical CAD model' style. This is a craft from my books, and was weirdly popular among the ToughSF people.
An absurd little kitbash. The giant Compensator 9000 guns are the PD weapons on the Unnamed above. I used it to trace a book cover.
A speed-modeling session I did in an afternoon produced this set - never used anywhere but I like how they turned out, individually.
A concept for a modernized revolver. The cylinder is a magazine you swap out to reload. Electric ignition. Low-set barrel. Rails everywhere. Massively forward center of mass but that's the cost of doing business.
This is an old one, but the color pallet is timeless.
Book covers! I make my own, because "It has to be JUST RIGHT, best make them myself..."
More REKT! Made this between sessions, very glad I got to use it. Trace of a scene from Overlord!
No matter what anyone says, my meme style IS ART! It IS! I SWEAR!
A major pain-in-the-rear project I WILL finish, one day. Soon. I rolled back the baseline model for simplicity, and need to change the hull volume a bit before I continue filling internals.
Drake, from my books. I was really useful to draw him, so I could write him better.
People, also from the books. Describing an alien or person is easier when I can look at them.
WIP! Starship Victory, from the Lost Starship series by Vaughn Heppner. Fan art of my own interpetation, since no proper official art exists!
Sprint! I want to practice this simplistic art style more, honestly. It works well, I think.
Map! Because I really like making those.
Comedy posters for Nebulous: Fleet Command.
And finally, some sketches.
Pudding!
