MOAR HELP.

Tsu is better-sounding when pronounced halfway between "ts" in the "tsu" and "z" in 子. Or, like, when you're irritated and you say "Tsk!"
Also, don't put dramatic stress on your plosives - don't say the "t"s and the "p"s like an American. Soften them, not to the point of saying "Doudemo" instead of "Totemo", but certainly not "Tou!-tei!-mow".
Additionally, in the post down below I asked for the waveform (the heart-rate up-down visual you see in your recording) to be close to the "ceiling" and "floor". I'm not asking you to shout, I'm asking you to project. Drama and Choir members especially - can't do it, get scolded ahaha. |D Also, it's okay if the peaks don't reach as high as the one in the picture. If you really tried your best and can't do it, then (click the picture, there are words on it!):

Over and out,

Shichi-sensei.
