More detailed graphics

We started to do some detailed graphics today with the water, background image and the main menu. The origami style have been quite challenging because it's hard to define how many geometries we should use for each object. The frog itself got less geometries than the tree in the background which can maybe look weird in the end. 

Maybe we will have to have the most important graphics as detailed as possible so they stick out more and have the background etc less detailed. Right now we don't really consider the color saturation, it will be changed in a later phase.
