Not bad for your first attempt ALLKAR. I did notice you used a water color filter (or something like it) on the rims and chrome so it would not look like a photo. Which is fine, but maybe a little less on the pixel area.
Also, Z is right on the resolution. I work with a minimum of 300 dpi. A maximum of 600 dpi. I do not recommend 600 if your computer is a few years old or has less than a gig of ram. 300 will be sufficient, you could almost get away with 200 dpi.
I also can use up to 200-230 layers, but I am always using shortcuts to minimize that.
Color choice is great. It will take time to master a few techniques, but keep it up. Some great tips are on http://cardesignnews.com
Look under "Process" tab at the top...scroll down to "tutorials".

Thanks for the tut site. I'll try working with a higher dpi. I don't think I have the patience or computer power for 200+ layers. I'm just playing, on my laptop.
