ok lets see what i got up my sleeves...
there are lots of poofy skirts you might be interested in. the lolita ones and the ayumui ones come to mind first. i would also recommend getting the imperial regality CI as it has head wings and ankle wings that you might be interested in. as for birds, im afraid your right, there is a limited supply of birds on meme... there is the DayDreams CI that has birds in it, the Winter birds EI that has lovely blue birds in it and a variety of chickens ranging from rubber to chicks. there is a nice bunny that you can get though.
if you would like, i can try to make you a dream avatar.... give me a few moments though ok? and i dont need gold as a reward for making a dream avatar, your gratitude is enough for me.
