I'm with the other guys... Not enough map, too much "empty" space.
Zoom in on the map, and then shrink your dragon (and it's a beautifully done dragon, by the way) down so you can wrap him around just one corner of the map or perhaps perch him across the rounded top of the map, instead of the whole thing... Or, if you can manage it, put the dragon inside the map, wrapped around a compass rose or legend.
