A good start - I liked the musical ideas in here. Me-as-future-listener-in-game appreciates that each element takes a while to get introduced, especially in tracks 1 and 3. Me-as-current-listener-in-jam would probably suggest taking some of the musical ideas (like the addition of the choir in tracks 1 and 3) and bringing them in a little more quickly to get them into the listener's ears faster, and maybe from there either move onto the next track (show variety) or take the existing soundfloor and either introduce some changes to the chord progression, maybe a key change, or some dynamic variety, give us highs-and-lows. The ideas are strong enough that you have a lot of flexibility in how you choose to execute them, so you can really build them up from here.
