NinjaLA has a couple more test renders for his Wing Commander comic. This time he's created a cel-shaded Dralthi and pitted it against a Hornet. You can see the progression from initial black and white concept to colorized space battle below. Ninja's currently on a business trip where he hopes to continue his drawing and make more progress on the project. Check out his Rapier here.
Here's the Dralthi I made for the webcomic. It's the version I'll probably end up using.
