I like it. Great idea!
To put more of the map area int ouse though I'd add bases to the outside of the outer ring and create openings in the outer ring to allow the fleets out. Maybe also add another ring outside the current outer ring, again, with bases on both sides with openings for the fleets near the ears on each side.
BTW, it reminded me of Mickey Mouse too. Call it FiLtHy Mouse

Kind of Telletubby-like too... maybe FiLtHytubby would be better.
