The ice shard graphics should be improved, in particular the graphics on the building once it has been constructed on top of the ice shard. Other resources, once constructed, will turn the color of the faction owning it through influence. However, the ice shard has only a tiny speck of colour to display ownership and construction being completed.

In its built stage it is barely discernable from a non-constructed ice shard.
