"Lengthways on a rainbow" from a diptych "Tsiolkovsky's Worlds"

My picture "Lengthways on a Rainbow" is a part of a diptych about Konstantin Tsiolkovsky "Tsiolkovskys Worlds". The picture "Space Workshop." has to be the second picture Konstantin Tsiolkovsky is a founder of astronautics. He is my fellow countryman as was born in Russia in the city of the Ryazan region.
