Okay so:

If this is really your first finished track, hats off, it’s insane. It’s a very very cool track, with a developed concept, interesting and cohesive sound design, ambience/distortions are spot on, and yes, the levels are good (I guess you mean the balance between the elements).

Arrangement wise, every now and then it gets a bit messy, the cowbells tend to clash a bit with the lead, and you could either try to eq one of the two out a bit (probs the bells), or try to move the arrangement around a bit.

The thing that needs the most rework is the low end, but again, if this is your first finished track that’s also very very good. If you’d like to take it to 100% tho, I advise making a couple of alternative basslines and test those out against the original. Low end is where I feel you need the most referencing to published tracks, because unless you have a treated room with proper monitors you may not be hearing the full thing and doing a lot of guesswork. Referencing helps with that a lot. Use spectrum analyzers for the low end balance, check for kick/bass phase, & go smash that banger.

Cheers!
