Reply to Recorded a mix and then found the most minimal wave form. What did I do wrong?

This is the first mix I've ever recorded-- I appreciate the help. This test mix has the most minimal wave form; is that a bad thing? If so, how bad? Here's a screenshot of the mix on the top left:

I reckon the opposite waveform is what mine should look like.

I recorded my set to a Zoom H4n. The recording was encoded as 320 kbps MP3 at 44.1 khz. I used TRS inputs from my Novation Twitch to the H4n using the Master outs. The levels shown on the H4n didn't go above 3/4ths.

Additionally, when I play the mix, the sound levels are extremely low.

This mix is intended for Soundcloud listening.

What should I do to improve my mix?

Thanks.
