I really like the laid back groove and I agree with you that the heavy bass and kick allow me to imagine a stomping dinosaur really well! I really like the change in percussion and the melody that emerges in the piano about halfway through. I find that repetition is a helpful tool, and having different parts separating the repeated section makes the return to the part that’s familiar so much sweeter. I wonder if a B section in between the change up in the main part would allow for even more satisfaction from the listener when you get to the melody part. Overall great work and thank you for sharing!
