Stickers – what to note ?

Now I came to the funnel to glue the car with stickers and foil itself. So rally numbers on the car doors, tiger head or skull on bonnet, sponsor stickers from motor oil companies, colorful (multicolored) decorative stripes, favorite bands, comic characters( Batman, Superman, Mickey Mouse etc…) etc. . I have no experience with it, just think that it is easier, cheaper and more individual if I myself mac he. On the whole I have colorful rally cars in mind. I want to include as little as possible (in the absence of experience, especially with curves, like wheel houses) the author’s edges. Wrapping equipment( rake, scalpel etc….) I have. Is there anything to say about this ?
