It feels rather empty.
I found myself zoning out heavily between the 2 and 3 minute mark. Not in the good way though.
In my opinion, adding increasing melodic layers (not too many), harmonies, perhaps some effects, more variation on the drums etc. in that part specifically would really help it out. However, it should be noted that I am incredibly tired and running mostly on coffee at this point in time.
Regardless, I still enjoy the tune.
