OK. Nice portrait.
As for the authenticity - here is some short in-depth hat analysis for those who would want to fool a Russian with a fur hat, which is not easy.
There were two types of Soviet adult ushanka hats - military and civilian.
Military hats had an emblem which is a red star in a golden laurel wreath, or just a red star with a hammer and sickle. A genuine military ushanka was immediately recognised as it was omnipresent in the streets and they all had the same design. There were also semi-military hats like railroad workers, pilots etc, but we will put that aside as it was not really common.
Civilian hats never had any emblem, badge or symbol. It was always plain. It would not even cross the Soviet's mind to put some badge on a fur hat unless it is a military uniform.
The civilian hats with badges were pure foreign invention modelled on Soviet military hats and reintroduced to the Russian followers of fashion in the 1990-s and were gladly accepted.
Civilian ushankas were (with rare exception) made of natural fur - sheepskin, rabbit, fox, muskrat, mink, and sometimes more exotic, like polar wolf ( this one looks great and cost a monthly salary easy).
Ushanka hats were being worn by Soviets with ear flaps tied up at the crest of a hat - always! It sort of defeated its purpose and design, but wearing it with flaps down considered not really manly and was akin of wearing unzipped pants. It was basically considered better to freeze your ears to the stage where they start falling off than to untie the flaps and reveal yourself as a bloody peasant or a, well, foreigner. Foreigners were immediately recognised by the Soviets by the funny way they were wearing their ushankas - with the flaps down.
By now, ladies and gentlemen, you have realised that the ushanka hat in the picture can not be possibly Russian. It has no laces and simply can not be tied up. What would a Soviet man do with this hat? Probably would have glued the flaps to the top.
The second feature in this image is the Adidas hoodie. Adidas garments were quite exotic back in USSR and have even earned a two-line poem:
Тот, кто носит адидас,
Завтра родину продаст.
Which rhymes perfectly and can be translated as:
Those who's wearing Adidas
Will sell their Motherland tomorrow
I do not know where it came from, but it was a widespread joke, and for many Soviets an ushanka and Adidas in one package would have some ironic connotations.
The background is fine - typical Soviet curtains

The beard though is probably trimmed too well.
