Hi Dmitry, welcome to the forum.
Got to say your work is fantastic! Some of the best work I have seen posted here!
As is so often said in this hallowed forum "The Irish games industry is small". If any freelance work does come up though I think you portfolio would bump you to the front of the list. Check the company list on this site and blast off a few emails.
Though you may want to consider also making contacts in the advertising industry – can’t hurt to cover your bases. Why not email graphic design agencies your portfolio (I got a job that way a few years back) – for that though you would need to show further real life products modeled in 3d and perhaps your portfolio could use some more buildings – 3D rendering of buildings is big with Irish auctioneers. I know that is not animating which is what you seem to excel at but a pay check is a pay check.
Best of luck.
