I disagree with the other anon. Basing for 6mm minis can be a little exaggerated to read better at table height. I've been putting off doing more work on the lads environs here while I've been busy painting them up still, but I think you've done a good job of providing a mix of textures and shapes with your bases to make it seem like a real environment.
So long as you're treating them like large brushgrass, ferns and bushes, the tufts work great. I would say for the hovercraft though that they look a bit cluttered except if they're explicitly to be a jungle environment.
Overall I quite like how yours are turning out; the concertina is an excellent touch and gives a solid 'battlefield' vibe that might otherwise be lacking and other manufactured wartime clutter would be good to tie other stands together.
