Lens Flare, Alpha image Grass and Skybox

In the game there are some assets or background that helps improves the game play, like the weather snow or rain; background day or night and water, tree, wind and grass.

In my map i have added the following to enhance landscape of my map.

The first i added in the sky-box, having a sky-box will make your map have a thing to look up to then just simple blackness.

Secondly i had place a lens flare in the air, directly centered and beneath the brightest spot in the sky-box. this will have the effect of the sun is right where the brightest part is and threes a reflection of the light shining on your eyes.

In games their will be grass sometimes, but being a simple picture or texture will be dull. So unity have an asset of grass in Alpha Image. This makes the grass more realistic as it moves with the wind and 3-dimensional view.
