I really loved Whirlwind polish. It's just beautiful. Also, Feline Kohl Power is awesome, but if you're happy with something that you use now I'd wait and get it with McQueen. Blue Storm is awesome, it looks like a mix between Freshwater and Deep Truth in the pot, but it goes on a little more purpley. I did get Thunder, but it looks VERY similar to Mystical Mist and Fertile (which are both LE) I did get Atmospheric lipglass because it's too unique for me to pass up. I passed on Cumulus because I have Rondelle and they're TOO similar for me, and Cloudburst cause I have Black Tied and i never use it. I passed on both quads only cause I have enough shadows to make a black or brown smokey eye as it is and I don't wear it that often. I don't have Plumage to compare, but I did get Stormwatch and I really like it. I didn't get any other lipsitcks/glasses cause I'm not too much of a nude lips girl but I might go back for soft and slow.
It all just depends on what you would wear often enough, or what you think you might regret passing on later. Do you wear/have enough blues or purples to pass on Thunder and Blue Storm? Do you really need another black liner? Will you really wear a purple or silver lipglass? Do you need some more nude lipsticks?
Sorry that was long! That's the way I always sit and figure out what I really need to get if I'm low on money. It's always hard for me to narrow things down but sometimes it must be done!
I hope that helps narrow it down even just a little!
