Is it just me or are they oddly square?

Because they only reveal a partial design. As written: Banknote Concept.

These Are Nice! I Much Prefer These To The Current Banknotes!

I like the £10 and the £20 a lot more than the £5, simply because the image is a photo of Churchill, rather than a drawing, and it reminds me of a novelty note.

Just glad it's not a full colour photo.
