Definitely needs a little more detailing, but this already looks like loads of fun! I'd suggest adding some height variation to your cliffs so they don't have that straight edge on the top and then adding some more details like the grunt in the crate. A great method for giving a map more zest is to give each area a 'story'. Just in the sense that you can look at the area and see exactly what has happened. Maybe some grunts were ambushed whilst they were having a barbecue or maybe a security guard was trying to escape on a quad bike when a headcrab made him swerve and hit a cliff. Little stories that give the map atmosphere will really add context to what is already a great looking map.
The container with the dead grunt is a nice addition! Though you still have to work the cliffs and the hole in the middle of the map.
Keep going!
