I listened to your mix and could hear what you meant within seconds of listening...respectfully speaking.
EQ in general:
Your levels are great, and ironically, your low end is actually rather tight...I'd probably control it a little more with some multi band compression though--- There are several issues you'll need to work on to get your mixes to breath and pop. For one, your low mids that are causing some issues. Go back to your tracks and check out whats going on between 200-500...there is a lot of energy build up in that frequency range that is definitely muffling things. After that, try cleaning up the 650-850 range as well... Try listening to competitive reference tracks as much as possible when it comes to equalizing...
Mid/Side EQ & Left/Right EQ:
I'm curious how your panning looks... I'm sure that once you clean those kids out better that the mix will immediately become wider. Are you familiar with Mid/Side EQ or Left/Right EQ? I can hear some mids in that lower flute pad that don't exactly need to be carved with a stereo EQ...instead I would try either a Mid/Side EQ or Left/Right EQ, depending on where you have that instrument panned. Try utilizing Mid/Side EQ or Left/Right EQ more in your mixes vs just using standard Stereo EQ...you're able to carve a bit more precise.
Multi Band Compression:
Your sub bass could definitely use some Multi Band Compression. Obviously you want to hear the sub, but you also do want it to overpower your song...unless thats what you're going for... Sometimes a Multi Band Compressor can serve a better precision tool when dialing in your compression on a specific instrument.
Distortion:
This is huge...no pun intended. Harmonic distortion is soooooo overlooked in mixing by most. For example, your kick sounds fantastic; buts its so plain and doesn't stand out. Try adding some harmonic distortion to give it more character to pop in the lows and as well as the 2k-4k range. Harmonic distortion is applicable on almost any sound and can most certainly bring any sound to life. In this particular track, your kick and sub have to many similar sonic characteristics. Adding the distortion to the kick could definitely help it bite in your mix.
Tuning you Verbs and Delays:
Don't get me wrong, you don't HAVE to do this but it definitely helps until you have a clear picture of your verbs and delays... Set up a pink noise track and send you verbs and delays to the pink noise. Obviously check each verb and delay, one at a time... You'll easily be able to hear what frequencies need to be cut out of your verbs and delays what trying to make pink noise sound good
Parallel Compression & Parallel EQ Compression:
I wait as long as possible to add Parallel Compression...I'd rather not overload my signal with "unwanted" frequencies, so try your best to clean your tracks as best as possible before adding Parallel Compression. Another trick is to place an EQ before the compressor you're using to send parallel compression to your tracks. This can help dial in specific areas of the spectrum you are trying to Parallel Compression...sometime Parallel Compressing the entire signal can be counter productive.
Sorry if I'm telling you things you're already aware of...these are just a few tips I can give hearing the mix you've shared. Let me know if I can be of further assistance
