Hey, ~I~ think you're doing great!!
The farkles are minimal (no big deal) and will go away as you get more relaxed, and there it is IMO.
As you relax, your phrasing will improve (which is already doing great, BTW) and everything will smooth out. Trust me.
Tone takes a while (and you pretty much have that nailed already) the same with articulation. What I've found is that it's the phrasing part that takes the most time, and there ain't any shortcuts, but I wouldn't worry; you're doing better than most. I think all you hafta work on is maybe your patience.
You'll get there. I'm proud of you!
