Having trouble getting the sound I want, any tips?

As an exercise to learn more mixing techniques, me and my band are trying to re-create a bunch of songs and get as close to the originals as possible to improve on ear training and force ourselves to learn mixing techniques that we need to get from point A to point B, and its really humbling to hear them side by side. (both shown in the video)

This is our first attempt, with "Paint the Town Blue" by Ashnikko. With the limited experience I have, I can't quite put my finger (or ear) on what can be done to get it closer to the original mix. I'd really appreciate if people on here with more experience can pick at it and let me know what things we can do to improve. Note, we're focusing on the instrumentals before we try tackling the same with vocal chains, so this one is only instrumental-focused-feedback we're looking for. Thanks in advance!
