I like the shot, the forms and flare catch my eye ... but it doesn't say "Heatwave" to me.
I found that microfiber cloth has a tendency to collect the stuff you swipe of the lens and will not become 100% clean. Over time, the small amount of foreign matter trapped in the fiber, can became an abrasive. I am not a handle-my-camera-gear-as-if-it-is-a museum-piece kinda of guy. (In the field some spit and shirt tail works for me.) But if you have the time, I think disposal, one-shot lens tissue is the best way to go.
