Well, finally finished it. I got delayed with a few things, plus the power outages due to the storm in Washington (luckily my house's power didn't go out, but it became a "refugee camp" for my relatives during the power outages.
I got a good practice with different coloring techniques that make this drawing look a lot better than the Silverado SS drawing that I had put up weeks ago. I'm still learning to use different colors on a car, so I use a lot of reference material to see what colors are visible on a car if it were black, sitting on the beach at sunset.
Other than that, I tried to go with a more aerodynamic design for the Tahoe SS. The front grille has bigger openings, and there is no "ledge" to show a separated area for the bumper. I had to raise the grille a little since the whole thing looked like a minivan. I think it looks fine now. I also widened the car's width with the thicker fender flares and took some design cues from the Tahoe Hybrid (the rear sports more flare for aerodynamics).
Again, I don't have a scanner, and I'll never be able to get one due to money, and the fact that big sized scanners are hard to get. So, you're gonna have to deal with the hazy photos.
Suggestions, tips, and criticism, welcome.
