Itinerary help

So I'm in Madagascar right now and still trying to figure out my itinerary. I'm in Diego right now planning on staying a couple more days before heading south. I'm gonna stop at Amber Mountain NP and Ankarana NP before heading to Nosy Be (Nosy Komba). From there I was planning on continuing south to Ankarafantsika NP and after that over to Andasibe NP (Mitsinjo). To me it seems as if I'd have a couple of days left so I was wondering if there's anything on the way, respectively not too far out of my way, that I should do?!
I'm flying out of Tana on October 11th.
I'd appreciate any recommendations provided!

Cheers,
Steph
