Hahaha! You are certainly not imagining anything. That is THE Rick Moranis cradling his maniacal talking plant Audrey II. I'm glad someone noticed! And so soon, hahah, I didn't think anyone would. Petshop of Horrors! That's totally the manga (which is awesome, BTW), while Little Shop of Horrors is the musical/movie. Aah, good times.
Hahah, I don't blame you (in regards to (#6), that's one of my favourites too. I just love Sho's face there.
Aaw, well, shucks. Thanks! Your feedback is awesome to read, I mean, especially since this is only my 2nd time making icons. If you're interested? I have more in my earlier posts in my journal, so yah. xD
Thanks again! Glad you liked 'em~ :)
