Well it certanly looks like an F150. 
What type of paint did you use for the side panels color? The color looks “spot on” for the Ford sides.
The next time when you need to paint a separate panel color, you might consider using some sort of masking tape. This would allow you to have a sharper line between the body and panel color. There are "low tack" (not as sticky) painters tape sold in many stores or the best is modeling tape like Tamiya Tape.
Regardless, even regular masking tape (clear/cellophane tape doesn’t work very well) could be used if you press it on a clean surface, like glass in a picture frame or window or even on your arm. Doing this several times will reduce the stickiness of the tape so it will pull off the surface easer and not be as likely to leave glue residue or pull up the paint of the other color.
By trying this type of technique you will have to worry less about how straight the lines are and can concentrate on getting your paint down evenly and smoothly. Depending on the type of paint (enamel, lacquer, acrylic) the time to remove the tape will vary. No matter which kind you used, removal should be done with a slow and steady pull –no yanking even at the end- 
.
I hope this gives you some “food for thought” so you can continue to advance your modeling skills on each model you build.
p.s. Many of us are still trying to figure out how to do this building and painting stuff too.
