If these are made by you their awesome, maybe you could work for me(paid) & still use the vector graphics you do, just make them more square(like normal square-based BYOND maps), not isometric like...(basically turn/rotate the fence....)
I work with bigger images like your doing there, in the range of 96*96 because im going to cater to players with high resolution displays but whos computer just may not be good enough for the latest games so they use it for BYOND instead....
Haha thank you guys, just download flash (trial version of course :D) and try by yourself. It's easier than it seems and you can make this way a nice, big graphics with alpha channel really fast. You just have to practice, i can help with any technical problems, but learnig how to draw is your job
