Wow... just saw this topic.
Er... thanks to everyone who mentioned me *blushes*.
Okay, now to my list of great set makers, which is going to be long:
Let's see, I'm always going to treasure that set Reverie did for me - I also love Hyperflutterby's - she just has a great knack for making beautiful graphics. Sakura also always does awesome work - for some reason, one of her pieces that stands out is Cassi's Giving Tree set. Yoshi.... is Yoshi, and has unbelievable create-from-scratch talents, which I greatly envy. I also love Rikio's work, even if I only did just find out she was a girl. Sorry! I love the pictures Robot uses, and the simplicity and elegance of her sets - she has such a beautiful unique, style. I also generally love the pictures Apricus uses for her sets, especially that city one she had a while back. Even though I haven't seen her around in a while, I always loved Mallory's work. Kim's stuff is also always great *flaunts gift set*.
Hmm... I absolutely adore Paola's set for LAQ a while back, and she's done a lot of other great work. ZH!'s set's are always unique and interesting, and Marissa's work is great (she's also one of the first graphics makers I remember from when I came to the forum). Um... ahoteinrun's drawing skills leave me in complete awe. So do Shollia's. And I love the avs Chass contributed to the gallery. I love the LJ icon Fzun made for me. Koku and Spira make awesome sets. Rageaholic doesn't do a lot of work, but all of her sets are great (and usually hilarious). And sort of a blast to the past, but Lina Blade's sets were fabulous.
...why do I have the horrible feeling I'm forgetting someone?
Well, if I am, don't worry, you're still great anyhow!
