I made this BT-5 and sunflowers diorama many years ago. The 1/35 BT-5 is the old Zvezda model, while the German soldier is a Hornet product. The sunflowers were scratchbuilt using paper and wire and the remains of the two crewmen were also built from scratch; they were some of the first figures that I ever sculpted.
The inspiration for this diorama was a photo in one of the old Time-Life World War Two books of a Soviet tank standing in a field of newly grown sunflowers. The sunflowers very much suggest the Russian steppe to me, while the presence of the unfortunate crewmen, while shocking, is meant as a counterpoint to the living sunflowers.
I hope you guys like it!
