Compare that to my latest Youtube video...
This mix is EMBARRESSING... super thin 
The mix in OP is better but I'm not sure if I'm doing everything right
That's not too bad! 
I think the first easy tweak I'd try is to simply raise the level of the bass track - I think it's too low
I still dont get enough low end but its mudding up the sound!!!
Compare that to like this...
It has WAY more bottom but still not muddy 
I like that last one the best, I think - but I like the bass to be prominent which may not be what you're looking for.
I think you need to step away from it for a week. Going from like to hate in five minutes is a sign that you need time apart right now
But other than that - get the bass to the right level - and THEN deal with the muddiness (which i don't necesarily think is too bad, actually). Though it may be a bit boxy. It's not exactly the same tone as the rhapsody track, but it's also fairly different in energy etc.
One thing to try - AFTER getting the rigt overall levels - is to put an EQ on the master buss and try to make some moves on that where you think you improve the overall sound Go for a few simple moves - the "big wins". Then copy that EQ to your guitar and bass tracks, and see which of those moves are suitable for each individual track - adjust from there. Not all those tracks will need it, but it can be a great help to go from big picture to smaller elements like that

I thiink Michael is right. Don´t hang into too long. Get your ears a break and build it up again.
sounds like over-compression, -limiting issues to me.
compare the waveform of your track to the one you posted as reference, which is much more open and breathing, whereas in yours everything is all the way to the front fighting for space without any dynamics left.
sorry to say so, but this is THE rookie mistake.
get rid of all those multiband limiters (especially in the sum) that were most likely used.
make a working mix first.
personally, I recommend reading The Mixing Engineer's Handbook by Bobby Owsinski
I'm not sure how I can compare an unmastered mix to a fully mastered song when referencing 
Also I look at the mater bus meter and it's not slammed it's still moving...
what else would you compare it to?
if the mastered one sounds more alive than the not mastered one - like in this case - you know something is up.
mastering a bad mix will make is sound worse in a way, with all the issues becoming more apparent, not better.
I compare it to various songs I have on my studio computer like Grave Digger, Judas Priest, Loudness etc etc
Here's latest... Not sure if this is any good either
I have now tried reamping because I believe the previous guitar sound was muddying the entire mix...
Tried a @sinmix 6262 profile 
My mixes sound like complete garbage so take my opinion with a grain of salt. Even though my hearing is pretty shot with highs, your mixes sound very bright to me.
I know... When I loewr the highs I just think everything sounds muddy!!!
This problem is super weird
If I dont have it bright, it just sounds muddy
It I dont boom up the lows, it sounds thin
I cannnot find a good mid-way
For me what I am working on is making the drums less bright. If the drums are bright, I add way too many highs on my guitars = bright mix.
I try... But I just feel like I'm loosing all definition in cymbals... When I compare to other recordings on computer, its just muddy in comparison, they have more highs WITHOUT being bright/hrasch. How do they even do that??? 
Ok now I'm giving up on having the same amp sound on the entire album.
Now I will reamp each song individuelly with different profiles... We will see if this is the right decision or if I'm going to go completely mad 
I have never gone so far before. Only adjusting different levels of gain on different song parts but never completely different amp sounds...
I got inspired to do this while listening to Iron Saviors debut album: almost every song has different amp sounds.
And to make me feel better, I actually think that some of the amp tones are complete junk, but they work well in the context of the mix.
So I have to try myself at this approach!
