Certainly not to bad at all. God knows I started out worse.

ы - difficult sound. Be sure to pronounce it as one sound not a sequence of multiple close approximations (you didn't particularly do this but some people do)
hard to criticize pronunciation of в портленде because it's a US city name; it almost can't sound Russian; just be sure to treat the в as part of the word following it -- "впортленде", and вгости

"во мгле"

your ж specifically seems to be coming out as a ʑ instead of ʐ. This means that you're probably using about 20% of the way back from the tip of your tongue to touch the roof, making it sound slightly palatalized (soft). Ж uses the very tip of the tongue, curled up and back and meeting (basically) perpendicular at a 45 degree angle to the center of the alveolar ridge.
ж is voiced ш, but NOT a voiced щ.

your к in купил is properly UNaspirated (sharp sounding)

только is a bit of a tough word for non natives for sure, not only do you need to make an ль sound, but you also need to squeeze it in before the к.

Notice the colloquial pronunciations drop it for ease

Reeeaaallly shoving those vowels into their appropriate corners helps a lot towards sounding native (especially stressed о's, since that particular sound is very un-English) You do this well in single syllable words

your 'х' is definitely better than it could be, some people seem to only be able to make a harsh gurgle sound, but yours is at least a soft hiss, however I think I hear it being a single unit too far back in the mouth. Yours is bordering on uvular, whereas х is a sound pronounced right where к touches down-- on the velum. Pronouncing хххк хк ххххк shouldn't move the tongue forward or back at all - just close and open slightly

позже is actually a pretty weird word. It is one of the uncommon examples of -зж- which can be pronounced ʑ (voiced щ)

I don't know how in the hell you pulled off нравится so well, do you already have experience with rolled r's?

кофе is a good example of two of the vowels that are very pushed into their respective spots. o and е are physically higher up in the mouth than the anomalous English equivalents.

ть in пригласить его was pretty good

unstressed vowels are pretty difficult to learn, pretty much takes a lot of hearing them, and unfortunately, didactic material tends to use a faux pronunciation that essentially stresses every syllable, even though nobody actually speaks that way; but as long as you're exposed to many different speech sources that'll just come with time
