Hi Pete
I think you’re definitely on the right path. Tracks are relevant to the styles you chose and composition and arrangements are good.
I would work more on sounds and mastering. They’re not bad and they may work as they are but I think that the overall level of production is getting higher. Pianos and drums could sound a bit more realistic, sample wise and with more dynamics: it’s a combination of better samples or plug ins and programming: there’s a lot of good stuff out there that’s not as expensive as it used to be. You can find great drum midi loops played by real drummers and that makes a lot of difference in some styles. Like I said before, they can definitely work for some libraries a and some styles as they are but there’s room for improvement.
