Nice ride, yet 1993 SLE was giving you some great info. The easiest way to take your pictures from just snapshots to images is by using a tripod. The tripod will take the super softness out of your images and help to give them punch and sharpness. I am yet to do my ride as a session takes some setup. The images I do have are from the dealership where even for their web images they use a tripod.
Using a tripod is to photography as changing oil is to auto'*. Not using one makes a big difference, just like not changing your oil will make a big difference. Get the picture.
