@ mastervk:
you could have tried making the bubbles using a mixture of shampoo and water. Did this very much when I was a kid, and many times got scolded for wasting the shampoo.
The two roses, IMO are looking over saturated. same with the third flower. Though, the lower half is looking good, the upper half isn't looking that great.
The last photo looks great. Especially, I liked the water.
