I just finished these and I'd like to share these as well as make them available for the guys that use my skins. These are sharpened and shaded versions of my Force Command and Space Marine. The FC had his face and hair modified a little and the SM has been simplified for other skinners to tweak as they like. Here are pics to show the difference between shaded and non-shaded models.
If you noticed the shaded models look a lot better especially if you're fond of chapters that use grey, yellow and white colors. The shading is based on the "Painter's Halo of Light" technique. If you paint TT models, you'll immediately grasp what I've done. Basically, I shaded the color layers based on the premise that light was present somewhere above the model. On some occasions, the models actually look like they have specular lighting on them. This technique is great as you have better looking models without taxing your computer's resources. If your computer can handle it, adding specular lighting to these make the models more beautiful.
I hope this little technique is considered by the skinning community as an added option in their future projects. Please post any feedbacks that you have so I can improve this technique further.
The skins can be downloaded here and they will be added to my site soon. (Banners and badges by Hangar-8)
