This is my first infiltration map and im quite pleased with it. I based it on one of those situations where you and a few allies are stuck on a hill surrounded by enemies.
good idea in concept, but the map isn't that great.
for an early map this is quite good :)
change your shading tecnique, and use a little darker colors(yours are very bright)
please, keep mapping :D
I think some shading in the bunker would be nice =) try changing the texture and the color of the map. Lime is not a good color for grass. But at the end, it isn't that bad to be your 1st one.
