Great addition to the vividly superb 'Ice cave' series.
With two central pool tiles (one with two cave columns on; the other with a small ice island on ) you have the ability to create a huge pool.
A shame that there is no generic 6x6 ice pool tile with no additional detail on. As to make a huge cave pool you have to replicate the two easily identified central pool tiles(with columns or an island) as mentioned above.
This set also contains two transition tiles to the Caves series, one of which is from an Ice cave corner, the other is from the centre of an Ice Cave Chamber.
Excellent set ! Well done Ed ! Any chance of the blank 6x6 pool tile though ?
