Recolours

Thrillingly for a GwP, we get two new elements in this set.

• 4x +1 spare Tile Round 1 x 1 Quarter in Trans-Dark Pink (6558904 | 25269)
• 4x Tile 1 x 2 with Groove in Satin Trans-Bright Green (6353610 | 3069b)

It's nice to get these common pieces in yet more vibrant hues, and the opalescent green is certainly appropriate for the subject matter.

The build

Bags 1 and 2 create the landscape, the detail of which surprised me as it is largely covered up in the final model. As with the previous diorama GwP, 40784 African Savanna the water is made more organic by placing angled plates on top. The unusual colours in the river are of course reflections of the aurora – a delightful touch. 

Bag 3 creates the sky, which is attached firmly to the brackets added in the earlier stages. This section uses both of the recolours, plus a round 1x1 tile which I was pleased to discover is a glow-in-the-dark element (6284592 | 35381). Another nice touch!

Bag 4 contains the foliage, and certainly qualifies as the "parts pack" of this GwP, as you create 4 small and 9 large snow-topped pine trees. The quantities are worth noting:

• 13x +1 spare Tile Round 1 x 1 with Hollow Bar in Reddish Brown (6186673 | 20482)
• 22x Equipment Candlestick in Dark Brown (6473752 | 37762)
• 26x +1 spare Plant, Flower Stem with Bottom Bar in Dark Green (6498565 | 24855), only in 5 other sets currently
• 13x +1 spare Plant, Flower Stem with Bottom Bar in White (6334087 | 24855)

With those plus some further small pieces added, the model is complete.

Verdict  

This is the only one out of the four LEGO Wonders of the Natural World Diorama Collection GwPs not to contain any animals, which is probably due to it being in microscale. 

Consequently the focus is very much on the trees, and they certainly dominate. I feel the model is a little cluttered, but obviously it's the simplest of modifications to thin out the forest.

By contrast, the aurorae are minimal, but convey the banded effect well, and the colours are spot on. As mentioned, I love the reflections. Tiles instead of plates would have made more sense there, but I expect the building instructions team would not be keen on having the similar blue and green tiles in the same bag. I suppose the studs do add a sense of sparkling water.

Our Finnish correspondent, Mr Okkonen was struck by the lack of snow. As I love on the other side of the world, I'm not so bothered by the lack of reality there, as the varied colours provide a lot of necessary visual interest. I'm not keen on the white tiles in the river though – combined with the transparent green and pink tiles, they make it look more like a magical pathway.

Those critiques aside, this is indeed a rather magical little diorama that will attract attention, and I'm happy to have these pieces in my collection.
