Nonstop Heat Logo (raw version)

yo, I’m asking for advice on this logo I’m working on, it’s a raw version and I want to add more details if the customer likes this concept so far, any suggestions on what I could add or how I could maybe give it a vector feeling… or even better: I made this logo in ps is it still possible to convert it into a SVG (sp? you know what I mean)? and what should I change?
