It's a very, very nice geography. Obviously quite well thought-out, with deserts and rainforests at the correct latitudes and all. Quite a few large impact craters as well, it appears.
I have created a kml file of your world to view it in Google Earth: Dogzilla.kml. One thing to notice is how the continents pinch a bit at the poles. You might want to redraw them slightly to avoid this problem. The best way (in my opinion) is to make sure the entire northern edge of your map is either all land or all water, and the same with the southern edge.
I'm excited to see where you take this, I think it's excellent. Have some rep.
