Good terrain with a good field layout for WW1. As Midi said, add some small, gradual elevation changes for a more realist look and fix up the water areas. They are hard to distinguish from land. Adding some depth to it and changing either the water color or texture underneath would make a world of difference. With that fixed, I see no reason why it couldn't be submitted to Skuzzy for the WW1 arena, it needs more.
Also, since the file size of WW1 terrains are so small due to hardly any objects needed, don't be afraid to experiment with custom terrain textures and make give your terrain a unique look. AHers love variety & don't get much of it.
