Egypt - Cool track. I like how this track just keeps flowing forward. Nice production. My only wish is that it were longer. It's really nice and progressive and feels like it could've taken those progressions even further. Great work! This one is probably my favourite.
Postcards - Nice and relaxing. I quite like that pillowy bass. It works well with the subtle keys you have going over it. Very relaxing this one. Also love those sweeping pads.
Merchant - I do like how those percussions indeed immediately remind me of a Merchant. A Merchant in the desert to be precise. Great work.
Very nice soundtrack. I imagine this one would work as videogame music extremely well because of its unobtrusive nature. That's not to say it's boring, it is definitely not boring. It is constantly evolving in a great way.
Awesome job!
