You can do Batman with just the N's without the A's :P He goes "use the secret knock" You "knock knock" He "who's there" You "me, let me in there is no secret knock" He "oh, ok come in"
This looks like a house where you have to have some sort of secret knock before you get in, like a secret society (plus the omega sign on the entrance, spooky Subby, spooky)
Dude, you're a little hard on yourself. There's always room to perfect something but you're nailing every single one of those photos, just awesome work adjustments or not. Pretty impressive skills
