I think I'm seeing everything all the same from too long staring, or the colours are not right, or I should put more? Red, blue and red should be there for sure, but maybe adding some yellow...? To make the images brighter with stronger contrast or not? Heelp~
Also...I think this is what I want my exterior establishing shot to be. I have to put some small details and to touch it here and there, to make it look more like "aqua park":D I'm planing to add slides and maybe some structures for filtering water or something of the sort, to make it more logical and realistic..? We will see where my ideas will fit! And this big bright mass behind is a waterfall.
