Hi Omri, nice stuff here
You could also add smaller versions of encounter maps for virtual tabletop playing... I would say something like grids of 70x70 (px) for Roll20 and 100x100 for FG, and two versions of each : One with grid visible and one without, as these softwares can add their own grid. For the one without grid, just let one square visible (in a place that doesn't interfere with the game, near a corner for instance) so that the game master can align his grid.
Looking forward to seeing more maps !
