And Atmosferas With Tuba and Mellophone played by me

Atmosfera was recorded at my home. I used an SM58 to capture the tuba sounds (noises?) and an out-of-tune melody of the mellophone.
I used Adobe audition for all the mixtures and high-pass filter.
I used the reverbs of CreativeLabs.
As usual give me some feedback
