nightscale and nursejoy both have beautiful sets of icons, but I love forgottenjester's hilarious genie icon and sootyowl's adorable owl and intrigueing's clever/funny set and queerwolf's gorgeous wolf and rubbertea's cute guy. (Even though IDK who the hell is in rubbertea's icons, he's cute. Which is enough reason for me to mention them.)

And of course agentcthulhu's, though that goes without saying. ghostofcairo's always kills me so I wish they showed up more often; they have excellent taste in general too.
