Great job, Jorgen! Wow!
I know how long you've been playing (and it ain't long!) and I'm really impressed with your tone quality and timbre, such a warm sound you're producing - I can tell you've been working hard on that. You're squeezing out some good 'grace notes' I see (difficult on bone as you can't help them along with the valves!) helped along by your good embouchure - you've got a great foundation from which to build now. If you want some constructive input then I would try and put a little bit more expression into it, not much more, just small things like a little more slide-vibrato at the end of each phrase and maybe try a short glissando up to the first note of each phrase just to give it a little more 'flavour'. But, like I said, that's a brilliant effort!
Now to the improvised section!
