the decals are pretty good, did you use paint?
No, but close. My method of custom decals is I sand it with a piece of normal sandpaper on the area that I want to decal, then I draw my custom decal on with Ultra Fine Tip Sharpie marker, then I spray the new decal with clear acrylic spray. Viola, a new decal! It's actually quite easy once you get the hang of it.
