Fossilized Relics: Awesome, you went for a more Eastern vibe I see, with the sitar (right?) and flutes. Really well executed too! You always manage to amaze me with what you can do. Copying a bit from Selkione's review, your song also got everything a song needs:
-you got multiple sections, to counter repetitiveness (0:00 to 0:58, and 0:58 to 1:19);
-you got good mastering: all instruments sound great and are not too loud/soft etc.;
-you nailed the theme by the flutes, sitar, and nice percussion (that I cannot name for the life of me);
-you got an interesting composition (chord progressions, etc.), to counter boredom;
-you got interesting quirks that make the song special (e.g. the speed-up at 0:58!). Just awesome.
Simering Springs: I thought "is he gonna do a hot spring theme in here?". Glad you didn't. Just a soothing Eastern song. Really (really) nice to listen to.
Prehistoric Romp: how do you manage to make three songs, all completely different, yet still fit the theme?? And all ±3-minutes as well. I cannot even make a single 2-minute song, damn. This sounds like a live jazz-band of sorts. What are these dino's doing at moonlight I wonder!
It surprises me that you haven't found yourself a job in music yet (or have you?!), as you are clearly outclassing most (or rather, all) of us here. Soon we'll have to consider banning you, because no-one else can win with you here haha! (that's a joke btw, I really like to have you here :)
