Thank you for giving it a listen and taking the time to give me some advice. Really appreciate it!
I indeed find the stereo field part of mixing/producing very difficult. I mix exclusively on cans (small thin walled apartment) which probably doesn't help much. I think the headphones that I use are also quite forgiving when it comes to mud (I usually don't hear it until I listen to it on someone else's sound system). I should probably read up and/or watch some tutorials on how to get better at this, because I think it is one of the things that is holding me back.
Anyways, thanks again! Loved your submission btw!
