I see I'm late to the party; however, Judit Vántsa's Express Train To Bereck is my all time favourite of this collection of yours. I could stare at it for long minutes and not be weary; the train, the field, the colours, I dare say it's perfection.

Do tell the answer to the riddle. I'm bad at them, but I'm also a cat that curiousity could murder.

Kudos!
