i respect the effort, and it sounds good! what fingerings are you using because i noticed that you skipped your sharp 3s/4s (what ever youre using) like f# c# g# d#. idk if you have a book telling you otherwise or something, but i would suggest maybe using 3 for f c g d and high 3 or low 4 for f# c# g# d#. thats all, i get the struggle chromatics steal sanity, and keep up the good work!
