Hey there, my first Post to the Shrinking side of this place. A new comic story just opened a week ago and yes I know, right now there is no shrunken women. But it is shrinking of some kind. They also said they will be starting to do GTS as well soon. Also they do take commissions for one-time drawings or short-comics.
Here is a link to their store and their DA account.
