It looks pretty good, although there is a bit of inconsistency with the way the outlines are used which makes it look weird -- some of the outlines are black, and some of them are just a slightly darker colour. Also the grid doesn't look like it has much importance? It looks like its trying to be tiles, but the circles of the island just make it seem like the grid is an overlay on top. Also, that bird looks a bit too colourful for a Seagull!
