It's cool, I just have always preferred the STX or the Harley valance over the entire cover is all. That's what's cool about 97's. His has the look of a Lightning, yet it's not covering the entire bumper. Nothing wrong with yours at all though.
Most bumper covers that I've seen are lower than an OEM valance. If you don't use a body kit, they can look like buck teeth. But with a body kit, they make a truck appear lower and everybody knows that always looks good.
