The hi-hat is so un-noticeable, unless you're looking for it. So definitely keep it. As for the other drums, I like them, they sound pretty sweet.
The overall song reminded me something of a rollercoaster tycoon soundtrack. Of course there wasn't any drums like these in that game, however there was certainly that fantasy feeling.
The little tune is an interesting test, I think the only thing that didn't feel as though it fit, was the bass that came in with the drums. It felt a little off-note at sometimes. Maybe that's just me though.
Anyways, I like this sir. It's very peaceful, yet still carries a nice beat. Cool stuff yo.
The bass... it sounded better on headphones, I think. I mixed this on little earbuds, so you could hear the notes in the bass differently. It's definitely something that could be fixed, but I'm not going to bother with it. Thanks for pointing that out, though.
I think "groovy ambient" is the sort of style I'm into right now. Merci pour cette critique!
Please contact me if you would like to use this in a project. We can discuss the details.
