Ok: Your doing Roshi's island right? Ok. You want an idea? Try the map from DBGT when Goku fights on Earth/ Planet Plant with all the smashed buildings if your an l33t mapper, or if you've just started try the map from where Goku fights Vegeta in the Saiyans Saga. No-one has done that map yet, the one with all the rock pillars, where Vegeta used Gallit Gun and Goku did KaioKen x 4. Or you could try the map where they were inside Buu's head. That'd be heavy. Anywhoo, good luck to ya kid.
P.S. The screenshot of your current map needs a lot more work....
