Hey! Finally noticing some of these threads - I've been terribly busy.
My background:I started doing freelance video game art in late 2007. Worked on a ton of random tiny projects. Joined up with some guys making a game part-time in 2009 or so which ended up becoming
Dungeons of Dredmor by
Gaslamp Games (which I'm one of three owning partners in; fun fact: 2/3 Gaslamp partners are portraits in Starfarer). I'm now working at Gaslamp fulltime as art director (with two art minions!); it's neat. I have less time than I used to to work on Starfarer, but I love the game and it's extremely rewarding to me to draw spaceships because I've been doing it constantly since I could hold a pencil. I grew up playing all those awesome games of the 90's, Master of Orion 1 and 2, Ascendancy, Darklands, etc.
Starfarer is the game I was born to draw. Seriously.
Technique:I use Photoshop for everything. Everything. ...along with a Wacom drawing tablet. I don't even draw on paper any more.
I start a ship by painting a sketch to figure out the mass, the feel, the mood, and the silhouette. From there I refine the painting, moving things around, getting the colours right, and putting in details such that they'll look good for the next step where I scale the painting down to the final in-game sprite size. Then I start pushing pixels. Often times I'll take a couple elements from other ships to paste on for a continuity of aesthetics -- all the turret mounts, usually engines, often command modules for mid-tech ships. This final stage in the process is a combination of pixel art and digital painting. (Funny thing, I've actually gotten a ton of practice at doing extremely small-scale digital painting due to drawing so many game icons, eg. spell icons for World of Warcraft [which I did not work on!] type stuff.) So along with a couple sizes of pixel brush, I'll shade with some softer brushes, dodge and burn and touch, use selective sharpening, and even just do a hard paintbrush here and there at low opacity for hull corrosion. (Adobe gave us this technology, there's no reason to limit myself to tiny palettes and a one-pixel brush.)
I could do another blog post on all this, I think. It'd be a really nice trick to do a time-lapse video of drawing a ship but I've never gotten the capture software to work very well...
Frankensteining my sprite work into new ship designs:I love it. Go nuts! (Though technically all the art belongs to Alex; he's totally on board with it too.)
