This multi-part tutorial discusses designing an epic starship in
Photoshop, starting with the silhouette, then moving on to refining the
shape, and ending in detailing. While the final results look
dimensional, 90% of the work is actually done in 2d in photoshop,
achieving 3d looking results with only the most minor 3d work involved.
Part 2 starts with taking one of the ship designs from part 1, coming
up with a story on which to base the function of the ship, refining the
shape, and then detailing the trench area.
