The BozDigital compressor is good on guitar and drums.
Just to add to what bitflipper's said, the youtube track sounds like the drums and maybe bass are panned off to the right. At least it does to my aging ears. The left hand channel seems to be lacking in energy and content compared to the right.
It's generally a good idea to put the drums, especially kick, and bass straight down the middle of the mix. Several reasons for this.
As frequencies get lower we're increasingly poor at working out where they're coming from. This effect starts somewhere around 400Hz and gets more noticeable as the frequency gets lower and we start to get a bit confised and things sound muddled. Putting the low frequencies down the middle deals with that.
The second reason is that there's a lot of punch and energy in the low end of a mix. Centralising it can add quite a lot of power without necessarily having to adjust the volume of the tracks concerned.
Another reason is something you probably won't spot on headphones. When sound comes out of stereo speakers what's coming out of the left one has an effect on what you hear coming out of the right. And the other way round. It's caused by sounds on different stereo channels being out of phase with each other so the peaks of one sound's waveform coincides with the troughs in anothers. As a result they kind of cancel each other out.
Low frequency sounds, stereo synth pads and strings are really prone to phasing problems, and things like cymbals, which are basically just noise, can cause it as well. If you've ever played on a stage in a venue where it doesn't matter how you adjust things or turn up amplifiers, you can't hear anything well enough because it's lost in the cymbal wash you'll know what I mean.
You won't spot it on headphones because the sound emited by one side doesn't interfere with the sound emited from the other because your head is between the sound sources. Phasing issues like this can only be heard using speakers. If your mix is ever listened to in mono (or almost mono, like laptop or ipad "stereo" speakers) they'll cancel each other out very strongly. One way to check is to listen to the mix on a single speaker. Another is to use a gonomiometer (I think there's one in Span) that will warn you about phase mis-matches between left and right and other things that can upset mono compatability.
If you're recreating the sound of the White Album of course, pan everything hard right or hard left. Stereo was new back then and EMI were **** sure you'd notice their very expensive nice new consoles were using it :-)
Nice vocals and video by the way. And there's no need to be ashamed of the mix at all. It's still a work in progress, and like writing a novel or painting, recording, mixing and mastering a track is one of those things that never really gets finished, you just have to decide at some point that "it will have to do" and move on to doing the next.
