Although I'm more a graphics guy, I would like to share with you some gameplay thoughts I have looking at your map.
Timur and Selatan should be swapped according to the info I found on the web (http://upload.wikimedia.org/wikipedia/c ... _timur.png
, http://upload.wikimedia.org/wikipedia/c ... elatan.png
). Grogol should be named Grogol Petamburan, what you have now as Johar should be Sawah according your borders and Sawah could be Johar or Kemayoran.
You current impassables force the players to run to the centre that in general is a good thing, said that I think you should add also some other connections to create some other viable access to the various zones. For example Penjaringan could have a connections with Cengkareng.
Also in general bonuses that have more than 7 regions are terrible headaches, to prevent this your current Selatan can be splitted in two parts (north and south) of 5 regions; Right now take and hold a 10 regions territories/4 borders for 6 troop is a bit hard to achieve so players would certainly run to kill the opponents instead of trying to grab the bonus.
Maybe a split could be done also for your current Timur, maybe a 5 regions zone and one of 4. If you split it you can think to add also a connection with Barat, maybe lama- kebon juruk or baru-kebon juruk.
Right now the most convenient place to start is the north zone, all the other places needs an accurate plan to take and hold them forcing the players to run down the bottlenecks and fight in the middle hping that the dice will help them to delete the opponents.
Graphically speaking, the background is nice, in general I like it, maybe I suggest you to have less thick-dark black lines on it, if it works with your map outline it is probably too much for the artwork in the background, specially on the left side where you have brown tones (http://gyazo.com/23e46db147dcfaf4376809 ... 1327246308
). On the right side, where you have more green they looks fine (http://gyazo.com/ab0e0eabfe7de3b4715fd0 ... 1327246905
Looking forward your next update
