Her Live Journal is here, and while Google Translate is a bit murky at times, at least you can get the main sense of her entries. I am not sure how tall the dolls are, but they are so beautifully painted they are well worth a visit. Loseva writes that she "paints with a magnifying glass" and I believe it, since the details are so perfect--the girls are very "alive" looking. Loseva also makes the beautiful clothing!
So far I haven't figured out how to contact her, but here are her store policies, and if you log into the page with facebook you may be able to leave a comment, and hopefully she can translate it. It looks like she will cast a few and then sell the already completed dolls from her Journal. PayPal does not seem to be an option?
Here's a blogspot page about her dolls and her process:
And here is her Facebook page:
As of March 2016, she is on Den of Angels so if you are also a member you can drop her a PM!
