Hi there,
Great song, and a fine effort from your side to start learning it. It’s quite tricky to play with a clean tone as well as using your fingers on the right hand.
I would like to offer some constructive feedback as well; First of all, like David recommends above, I would also suggest that you “zoom in” on smaller sections and try to make them really good. Despite it being a good effort there are lots and lots of imprecisions and mistakes left in your playing. It is, to me, quite clear that with this song you’re trying for something that is still above your “comfort zone” 
Which is perfectly fine - in fact I believe we learn best by challenging ourselves. But it’s also important to apply our own “critical ear” to the result, and then work in a focused way to get better.
One concrete thing I believe you should do it look at your right hand positioning. In your recording you can often hear a lot of open strings sounding when they shouldn’t - that’s due to a lack of proper muting. You can see that, due to the angle in which you keep your right hand, that most of the time D,A and E strings are not touched by any flesh, and will therefore pick up unwanted vibrations very easily. You’ll basically want to mute those with the palm of your right hand.
On top op that, I can hear that your left and right hands are not in sync - meaning, you do not always pluck the string when it’s actually pressed down with your fretting hand. That leads to dull/muted notes, where they should ring out cleanly. On the right hand I think some of this is, again, due to that angle you keep it in. With no anchoring the hand is “flying” freely, and it becomes a lot harder to steer it to pluck the right string at the exact right location.
I once recorded a video of me playing a song in the style of Knopfler (in fact inspired a lot by this tune), and I will drop a link here… perhaps you can pick up some of what I’m talking about from it. Perhaps check out how my right hand moves between the string, and how it’s always muting all the string I don’t want to hear ringing out.
There are many example of this, but perhaps check the small section from approx 0:44 to 0:50.
Notice that when I play the arpeggio (from low to higher strings) I do want the strings to ring out together - so I change the angle of my hand to an “open” position… but as soon as I pluck the bend on that high string, I change the hand back to mute the other strings again… so only the wanted note, the bend, is left to ring. Stuff like that…
Otherwise, good luck! Playing this style of music is super fun and satisfying!
(Nice guitar btw!
