above are some of the sketches i done after they have been put into illustrator. i experimented with colour and i also decided that they looked better without a black outline. although this could prove to be a problem when I start developing scenery as I don't want the fish to blend into the background. I also still don't know the feel of my game so some of the colours used here may be inappropriate.

I am also not sure on the type of fish to use yet so this is something I have still to look into.
