Very nice looking site and like everyone else the slideshow was slow to load.
I did not see the social media buttons until I came back here and saw that Jill mentioned them. For some reason my eye’s never go to the far left. Personally I would place them on the right side.
You also need to add an H1 tag and some H2 tags to the page, you have 8-H3 tags and 17 -H4 tags
For Language you’re showing: en-gb
Detected in ‘lang’ attribute of HTML tag: [en-gb]
You need to change that to Russian so that the search engines know the correct language of the site.
Hope this helps.
