OK. Me and a few clan mates are helping Jagex fix up the clan world a bit by introducing a new type of clan war arena portal (which simulates the real wilderness only your wars can't be crshed by No Honour Clans, and other small differences. The rewards system is also different, includeing tanking staffs, binding gloves, etc.)

We want to make the display look nice as well, and I'm not going to say I'm the best pixel artist around (I'm not even a pixel artist, who am I kidding?)
What I need help on is making this map design look realistic, like the world map in RuneScape, to catch peoples atteniton.

The map layout is here, as you can see it doesn't look even close to real. If anyone can make it look like a RuneScape world map with shading areas of lights and darks, and really just making it look real, I would appreciate that to no end, and would get recognition in the posts we make. Thanks a bunch.

The Map:



It's big I know, but I really need help. PLEASE.
