Nice work first time out.
My suggestions.
Cut back on the reverb as has already been mentioned. Even though you may like it personally, it's about the song.... as a guitarist I like to hear guitars, but as a producer on my projects I can't do that....
Second.... your voice is good, turn it up a bit..... I wanted to hear it better.
to squeeze a bit of volume out of the mix..... insert a plug in to the master bus FX bin. Right click it (the bin) and select audio FX... look for cakewalk and find the compressor/gate. click to add it, and then select the MIX COMPRESSION preset. It's a good place to start. You will hear an immediate boost to the levels.
there's a bunch to learn but learn one thing at a time. for now.... it's a good start.
