The scene above is all Gimp. I looked into a vector drawing tool, but I quickly lost the patience to learn the software. Plus, using Gimp for everything keeps the graphics consistent. I drew everything flat, then distorted it. It could have been better. You can see how some of the bolts on the floor are stretched more than others, and the domed glass looks flat. I'm learning Blender for another project, so in the future my 3D images may be 3D rendered. This, however, will stay as it is in the interest of releasing this level soon.
Edit: 21Sept2011: Wow, almost two months since my last update! Spent 4 hours today making a single cutscene image. I've been drawing Juni figures based on photos my sister modeled for. I'm considering cheating for the rest and just using filters on the photos themselves. We'll see. I can't seem to allow myself to lower the bar I've set, but I really want to publish the final product.
I have been working on it, but very slowly. Thanks for the encouragement.
Edit: And, suddenly I've had a burst of diligence. One image until completion and 70% of that is done. It's 1:30 am here, but I'm going to keep working. I'm excited to be almost finished.
