I'm happy that you gave me this feedback. I agree with you about chords structure in first two tracks. I was afraid to lose that mysterious feel in the first one and since it's the OST for game I thought it doesn't need to have a lot of chord changes but I agree with you that I could add a little more in it. The second track should have been background music when the player go through the forest. So I tried to make it simple and without complex chord changes.
So thank you for your feedback, I'm sure that your remarks will help me to create better chord progressions^^
