If this was my model I would do the following.
Add some extra polies to the plant pot and add a chamfer or bevel to the lip just to smooth it some more.
Have some variation to the "flowers" no need to go mad but they look mathmatically too correct, vary the shape of some and the orientation of others and perhaps the scale.
Again with the flower heads may be add some colour variation to them, may have one or two going yellow and dying.
And to really set it off how about a dead flower head laying on the floor next to the pot.
