karmin you're so kind! Yes I think the tonguing is a bit better than it sounds, but I will think about it more. When I try to add more air on the D it just makes the previous A sound really forced.
laeta_puella It may just be the recording, but it sounds like you're tonguing very hard, almost as if every note is accented. I'd reccommend working on gently but clearly tonguing.
As to the D, try using lots of air when you go over the break- and practice hitting the note from scratch, without playing up to it. This may help you get better at hitting it in the jump.
