Little advice please!

Does this look realistic? If not, do you guys have any advice on what might make it look better?

Thanks! =)

It appears that a butterfly is sitting on a floating flower. There does not seem to be a seam which keeps it from being grounded.

Maybe a less busy background, the flowers get lost in the lines of the window pane and the way it is distorted in the bottle.
