It does not matter did the people like or not color profiles- they are very important no matter is it for web site, book or magazine. A lot of my financial income is from my color profiles. Buit this type of art are of more technical nature as well it use as base technical drawings for later layers of colors. Even more- perspective is not allowed there. There is from time to time some effort to add perspective but it never get into wide use.
About the same color profile there is two way in create it. one and most widely used is the vector based graphic and most used software is the Corel Draw and Adobe Illustrator. This method as result have plain colors areas with the just few add in the shadows. Other method is called full color art and for this is most widely used Adobe Photoshop and very rare Corel Photo Paint.
There is almost fierce antagonisam among the users of this two types of method of work. As I know vector method of work are in general used by those who are not much skilled in the true art and have no sense for this.
Also this give influence into the price of this type of art. Vector art cost some 5 to 10 USD per color profile while the full color art cost at least three times more. If you want to make real realistic work, with details close to the real airplane full color art is the only answer and there is no problem with price.
Tim- hope that I have answer on your interest in this subject and hope more people will give their input there.
By the way- I sell my art but I kindly provide also some free download for personal use. here you are and enjoy
