the first are bacteria deisgns for the game I am working on. Go play it here and give me some feedback (it is hard as hell :D http://tajono.de/Protectus/html/protectus.html
The second one is my first spacecraft design after the techniques I learned from Scott Robertson's book: How to draw. I wouldn't say it is great, but it is better than I expected. I was actually surprised by how easy it was. Check out this video and try it. Maybe you can already do it?
