Thanks for the comments guys:) I'm gonna see what I can do about the problems..
One thing, sand is highly reflective.. just look:
but in this case i should have some textures on it to the left yes.. because the reflections of the sky isnt that strong over there..
and for the receptions.. I cant give you my sources but I can give you some locations
new zealand, australia... just search around (it takes time) and you'll find what you'r looking for.. One more thing.. you cant just search on the keyword jungle.. its better when you have a location as a keyword
