I’ve been pondering this sort of thing a lot. I’d like to somehow represent that “haze” of twigs on a still-living tree that has only shed its leaves for either winter or the dry season (depending on climate), as opposed to being a dead tree that has lost all its twigs along with the foliage. I’ll probably never figure out how to do it in a way that doesn’t compromise wargaming practicality, but it’s something of a “holy grail” for me to quest for, which is fun in itself.
Anyway, you’ve managed it better than I have so far. Good to hear those Chinese terrain products on eBay ship quickly.
