People hate getting slowed down so having a spawn limited to an island where the players have to cross a river is never fun. Also, I can't see what spawn 1 looks like from the pictures, but if it's an uphill walk just move it. You should (IMO) connect the spawn 2 with bridges, put team 1 in the southwest, turn the old spawn 1 into a mountain and litter the "cav area" with ruins instead.
I need to make a new map so my ideas kinda overfilled onto your thread, apologies :P
