Hi Adrian, Thanks a lot for your valuable comments. I think you are right, yah... it would have been stronger if it had been straight (upright). Actually, this is the original image (how it was shot)without any editing, I would have slightly angled it to look exact vertical. I'll keep this in mind next time!
This is an interesting image, Bhargav, simple elements combined in a pleasing way, with a splash of colour.
One thing that puzzled me, though, was the doorway being slightly out of the vertical. Is that the way it was? To my eyes, the image would be stronger if it had been presented dead upright.
