Thanks, Scatman; it’s always nice to get compliments from someone with as impressive a body of work as yours.
I will say with appropriate modesty that I think I have an eye for this kind of thing, but you’re right about practice (and a bit of unhealthy obsession, too, I’m sure) being important. I did about a dozen versions of the Sentinels logo – trying to hit on something that would have looked modern in the 70s/80s but would feel retro now. Reprisals at Maar Lake Citadel took months of scrapping whole illustrations and starting over completely because I just couldn’t get the “feel” right. For inspiration for the Granix ad, I looked through a ton of classic car ads in Google Images.
