Yeh I wasn't too sure how they would work, though I was reasonably happy with the outcome and prefer it over a top down circle for a tree trunk where your players look like they're running around on top of the tree canopy like it's Crouching Tiger Hidden Dragon Used them in a session and the players didn't have any problems working out what was what. It probably helps that we've always used screenshots from miniatures as our tokens (LotR/Warhammer/WotC, etc) which are side on pics as opposed to top down like some people use, so when they're against the isometric trees it gives an even better impression. For people using top down image tokens (VTT) or if this was used as a printed map with actual miniatures, then I can see how it's probably not as useful.

It was an experiment, but I think I'll stick with more traditional top down maps
