It is a balanced skirmish but the river crossing may not work well... Because it long playing will bring a stalemate except if trebuchets can hit the other side or you add another ford to cross the river. You may want to test that especially against human.
Even if you aren't good terraining, see some tutorials, others maps and experiment all that the map editor offer to you.
You can find yourself liking to make a nice looking terrain.

And its always good to remember
Good maps Take Time
The more time you put into the design the more amount of detail you can achieve.
