I've drifted away, for awhile, but will try to attend more to my Russian.

Oля, I must agree with Johanna and rocksmom, you sound charming and your accent is very light.

Trying to put my finger on exactly where it is, I think that, primarily, you still have a Russian "XO/ O;" it's fuller than an English or American one (I've always liked the sound, actually), as in "whole" and "love," "would." Your mouth and cheeks should be fairly flat, don't hold air in your cheeks at all.

The accent is extremely light, though, and in America you would be thought mysteriously exotic.
