This is my first Lego architecture line (a gift from a close relative), and as a Brit I'm jolly pleased to have received a cityscape of London.
The design is a smart, delicate, well thought-through build to a Lego architecture set. The shapes and subtle colour schemes of the miniature buildings balance with each other perfectly. To achieve such detail on a remarkably small-scale is very impressive.
Whilst the majority of the build was relatively straight forward, I found the building of the London Eye to be most tricky in terms of achieving symmetry with the 'pods' around the wheel. It's a clever design but the wheel does tend to wobble around a lot if being moved. But as it's a display piece I don't think this really matters.
It's worth remembering though, that although this set is designed for observation rather than 'play', the build can be dismantled at your discretion so you can make other things with the available bricks - it is Lego after all!
In conclusion this is a wonderful, impressively splendid model perfect for display.
