Yeah, the question is: What are your goals here?
Just an interesting map to explore in an easy-going fantasy game? In this case, the geography can be whatever you want it to be. (Just look at the first Final Fantasy games ... The maps are differing levels of bullshit, but appropriate for what these games are doing! :biggrin:)
Or something believable and perhaps even immersive? In this case, you need more basics and we need more background on your setting.
Either way, it's hard to say a lot about the shapes because the most interesting stuff (for gaming AND geography!) is missing. We would need at least the basic mountain ranges and perhaps also the biggest rivers, if you want to include these.
