Well I personally thinking that shadow is too harsh, try to reduce that by using Filter - Gaussian blur amount 5 - 8 (try).

Use burn tool on that side where light is not directly contacting to that object it will surely add more life to your composition.

Best of luck!

Thanks for the suggestions Adhir, But I want to show hard shadow & morning light so I didn't gaussian blur to it.

Very colorful! Pretty

I quite like this! It's a very pretty and appealing piece. For mine, it's a little out of balance though, with such a large 'vase' and such small flowers. It has a lovely illustrative feel to it, but I think that the 'photographed' bananas in front detract from this. Perhaps if they were drawn it might have made the piece a bit more cohesive.
Anyway, well done.
