Well, it's your first drawing and all, but I would suggest spending more effort in your drawings. 16 Minutes is very little. Therefore this lacks various details. For example, the grass is not that flat. It has blades of grass and different shades of green. The sky has different shades of blue. If there is a light source, then shading exists.

Anyways, welcome to.. (Drum roll please..) .. nevermind. Read the rules if you have not already and have fun. [X]
