Sorry if I sound harsh. I could say "it's fantastic" if that's what you wanted to hear - but that wouldn't be very helpful, would it?
Not sure if you can do much about it, but I don't like the name "aperture junkies"
Why associate your business with heroin addicts? I think this would appeal to far less clients than would be turned off/offended by it. I can't believe nobody has aired this point to you before you've taken your business this far.
I don't think all of your clients will get the connection with the word "aperture" either since I'd guess that a reasonable percentage of them (at least much lower than would know what a junkie was) wouldn't know what an aperture was.
client's customer: who's the photographer?
client: Oh, he's from Aperture Junkies.
client's customer: Oh OK.
Maybe you're targeting a particular demographic where this would work, but generally..... it's a big own goal, in my opinion. Sorry.
Also, what does your design say to me? Are you a nature photographer? A landscape photographer? An urban/architecture photographer? And what's that moon shot?
You have 4 unrelated, unconnected images as your first point of contact for many potential clients. This gives the message "a jack of all trades and a master of none." You're not distinguishing yourself from the 1000s of recent college photography grads who can "do everything reasonably for a good price"
The whole package seems a little unprofessional and suggests mediocrity.
Again, sorry if I sound harsh, but I hope it helps.
