Tatjana, thank you very much for your encouraging feedback.

Samrat, I am uploading the original version for you.

Grigoriy, I'm delighted by your visit and appreciation.

Tony, Myriad thanks for your observation. Now, I feel I did the correct thing to upload the B&W version, so that viewers can also concentrate on their action/inaction:-)
