Rejected.
You need to have bigger and more detailed builds, work with some different shapes, most of the builds you have atm are a bit on the square side.
Also, try using some different patterns and mix up the block types a bit more to add some complexity to these builds and future builds.
Have a look though some of the
accepted apps to see the sort of scale and detail we're looking for.
I do really like that boat captain sprite though.
