2. the 'horizon' at sunup/sundown, is always set at the level of your wings, makes things look wierd.. maybe this is because in real life, the sun is an object so big and so far awy, that it always is supposed to look like that.. ?but in that case, there needs to be something done about the horizon to make it look less awkward
