Nice mix Tony.
A couple of things I noticed. As Ajay suggested, the tambo is bit too dominant, although I think throughout, not just at the end. However, the shaker sounds absolutely great, so perhaps more shaker and a bit less tambo? It might be just personal prefs though.
The congas sound a tad too wide in the stereo field - perhaps a little un-natural as they tend to draw the focus away a bit.
On a technical note, there is a little click right at the end (3.59) well, at least you know I listened to the whole mix 🙂 a few times actually.
