What are you talking about--quiting the artsy shots!?!? These pictures are so unique and different. I've never seen anything resembling them in any other gallery. Don't worry about using the same effects over again, but it'd be nice to see some color variation. Try some other tints with monochromatic shots like #1 of this set. It looks amazing, but the color will soon lose it's appeal.
As for th first Chapparel, it's a work of art. Figuratively and literally, as I see you used some sort of paint brush-style filter. Looks wonderful. I like how the car is smack in the middle, but I hate symetrical shots. That's why it looks so good; the line is just slightly off-center and there's different stuff going on with the walls in the background. This is definitely a 10/10. Great work!
The second shot is a different style. It looks like a pencil drawing because if the outlines, but the noise and poor quality shadows (don't worry, it looks great) make it look like a picture taken during the actual car's hayday. This is another masterpiece.
Number 3 has yet another different effect to it. I can't remember the name, but I learned about a style of painting that was classified by thick black outlines, the use of black to fill empty space, and large, bright areas of a single color. The paintings looked a lot like this picture. The angle or composition might not be anything special, but the applied affect completely transforms it into a work of art almost.
You have got to keep editing pictures like this. It'd be awesome if this was your little style niche. I would also try other, newer things, but you should throw a picture or two like these into every update, along with some other styles. In my opinion you're the one cranking out the neatest stuff of all these picture people. All of these seem to make great wallpapers. Keep up the good work.
Actually, you should have a professional make large prints of these, then you could sell them as car art. I'd buy some, definitely.
And as a little note--I've told a few other epole this--you need to pay attention to your signature's position on the pic. Every now and then you might find it in a busy corner where it looks too cluttered. You should pay attention to that and put your name in a different corner if necessary. Of course, it doesn;t have to go in a corner at all. You could make it follow a line in the picture like many artists do. You could do all sorts of stuff, as long as it looks good.
