great instrument selection
but I agree, your structure is all over the place after the first minute.
it starts off so beautifully too! kinda weird how you introduce the drums and then cut them out as soon as you bring em in.
the drums themselves sound kinda weak, eq them so that they stand out a bit.
also, where's the bass? :d I'm a huge bass nut and am kinda disappointed that I'm not feeling -any- in this track. it's all mids-highs!
hmm, what happened at 2:40? volume just fades and song changes. sounded really odd.
generally when transitioning between segments you want the notes (at the end of the 8 bars you're leaving and start of the new 8 you're going into) you're playing to interact in a way that's either pleasing to the ears in a harmonic way for a smooth transition or makes a stark contrast and change drastically when going from style to style.
you've definitely got a great ear for melodies. start adding some basslines in and watch how it changes your thinking of harmony and structure. sometimes all you have to do is change the bassline to make a section different, while keeping the other elements. bass is a powerful thing. :)
