I spot so many familiar ponies but can't remember their names :/ and also don't remember the pony friends names. Here is some I noticed at first glance: gusty, seashell, firefly, munchy, up up and away, sweet tooth, fizzy, milky way, twisty tail, tropicana, SS paradise, heart trob, Princess Serena, ss wind whistler and cherry jubilee etc.

BUT who is that purple pony? That unicorn on the left side of the hip? Besides ss wind whisler, sky dance, ss north star(?). Is that boysenberry pie? Can't really see from that angle

So lovely picture 

oh lovelyyyy  congrats, they look great )

OMG! Absolutely stunnig! loov loov loov  very detailed, especially the headdress

hi and welcome back ) 
I'm also 90s child and looov g1 ponies (only got 3 g2 ponies). I have collected g1 ponies couple of months now after finding my childhood ponies.
You have such cool drawings! And you studys seems interesting!

My thought about their prices (I check them as euros and then change them to dollars, so might be little bit off):

Newborn Snookums in good condition can be up to 13USD, so this pony is under that because the flaws
Baby Blossom good coditioned have been sold even in 20-27USD but usually they sell for 6-13USD.. this pony is very common and her condition isn't perfect so someting like 6-9USD I would say..
Blossom. is she convace foot or flat foot? FF is more expensive. CF is common pony. Price range is 5-27USD- This pony could be maybe under 10USD (if she is CF, in FF little bit higher)
Firefly common, price range 6-13USD.. so this pony maybe 10USD or under
SS Buttons 9-15USD, price about 10USD.. maybe, not sure
Up, up and away common, price range 6-10USD.. your pony might be about 6USD

no idea about g2 ponies :/

Yummy! Yum yum is so pretty. You were so lucky to snatch it congrats 

question: is she twilight variation? or who is she ?

so pretty pony  and pricey I see

how cool is that! and scary  pretty custom indeed
