First off, your board is not the proper size. Your drawing board is 54 wide and 28 high, it should be only 53 wide and 28 high.
Your use of traditional Chinese decorations is really great and works well for this type of map. The paper lanterns and the dragon are characteristically whimsical and really embody the new year festival. The patterns on the banners are also highly festive, and reminiscent of that culture. I would have liked to see a little more variation in the trees, as having a few more shapes of leaf pattern would have added a lot more complexity to the map and made it appear more detailed. I like that the bushes and rocks as well as the river make the terrain not entirely flat, and the amount of tallgrass used is quite appropriate. Its is not overdone, it is not underdone. The map is simple, yet detailed, and has a great feel to it.
If you can make the board to be the right size, then your map will be accepted.
