I need a game background

Design details: I need a 360w-640h pixel background featuring a road leading to a castle on possibly a hill.
the background will be used as my game-menu.
I need it done by tomorrow, max 2 days.
this sketch will give you an image of what I want, but i am giving you a free hand:

a few bonuses will be be appreciated to enrich the background:
*a river flowing somewhere
*a peak to a medival vtown through the castle walls
* the game features emojis, so as a bonus you might place some well-known emojis as if they were characters(such as awesome-face) but it is not a must.
Target audience: everyone
Ideas for the visual style: medival castle, hills, green grass, rivers, emojis
