About that bird...it was like ... at first, I've decided to draw an Amazon rainforest ... but then I saw ( from the window) the snow is falling ... and then I've decided to draw winter ... so ... I don't know but maybe these hills are hills of Himalayas...
At the end I get from rainforests to Himalayas ... maybe ... but that bird is still there ... he will become a winter bird soon, and he will be undestroyable by winter ( hahahahaha!!!!! - evil laugh )
