Don't just use a random font and put a design above it, be more creative with the logo, cut it in have, sandwich the name VAPPIX between things, make a Badge with elements found in the Vaping culture. Coils, droppers, wire, subohm, mods (the actual e-cig device, pictured below) - I need variety, try something unique that combines vaping and photography with my name. -
See the images below, see how the blue vapor is exhaling like Frankenstien, that's cool, use that. Or how in the abstact images the Vapor trails go everywhere, that's a classic staple of my most popular work, use that.
But over all make it compact so I can use it on every image.
