Good graphics, guys. I'm no artist, but here's some ideas to consider.
1. I like the picture style of the Commander because some folks don't know what XK is until they get on a forum like this.
2. I wonder if due to the small size of a logo, if the basic shape of the Commander lines can be used with the details of shadows and such eliminated. More of a cartoon simplified approach? I'm not sure if anyone knows what I mean but if you do, what do you think?
3. I like the angle view as on the 07JeepXK sample.
In the attached Thumbnail, I just used paint to eliminate some shadows but I'm thinking of something with even more minimal lines. Any artists out there that think that would work, could you give it a try?
