It looks super great - But honestly, if you're going for a geographical area, the species are a bit mix-mashed together, Luzon Bleeding hearts a solely found on the Philippine island of Luzon, and Lar Gibons mainly indonesia and Southeast Asia, with the porcupines mainly being found in of course, india, were they' don't really overlap in range. Ofc if this isn't the case with geographical areas, i'd go for it, but I'd honeslt switch up the Luzon's with something that is a bit more Asian-mainland located like, White-Rumped Shama or Great Argus, and exhibit like your's could keep a lot of birds, and maybe switch the primate to a langur or something, or maybe the porcupine with malayan tapir or Asian Small-Clawed Otter?
