Umm....so, this has nothing, absolutely nothing to do with dinosaurs, palaeontology or science at all, but I just drew an imaginary fighter jet. Here's the rough sketch to the left.
I scanned this into my computer and used Illustrator to trace half the outline and coloured it all in and flipped a duplicate to make it all symmetrical. Then exported it as a gif and used Photoshop to add in the details like shades, scorches, and oil stains.
The result is below.
It's still rough but I was just having a bit of fun. I guess I could brush up on this technique and apply it to dinosaur drawings...that'd be pretty cool.
