Looks very nice. :bigups One suggestion I have is to remove the "specializing in" part on it. You can't really specialize in everything. In law school and medical school you take classes covering just about everything in their respective fields. However, you usually only come out specializing in one of them. You have a general knowledge of the other areas, but your focus is on one part. Like you are a brain surgeon even though you took classes in pediatrics. Or you are a criminal defense attorney even though you took classes in family law.
The point is that unless you have just as much experience in airplane and boat detailing as you do in normal car detailing then you can't really throw the 'specializing' word in there. Its a little deceptive. Then again, maybe you do have just as much experience in all areas. If that is the case then I would change it to "expert" or "Specializing in car care for:" or something like that. Just a suggestion. The card looks very nice. :bigups
