Hi Karl,
Yes, the shadowing can be adjusted, I do a version in between. Either way don't worry, I can also make adjustment when needed. As with the other designers, I would upload the required files and then there are additional files the we would send directly. You will probably want the logo also on a plain white field so that a local printer can make further adjustments such as color matching your vehicle or placing the logo on a website...
Please feel free to request anything else you may like to see.
Cheers.
