I was given this picture, that I would like to color. However, there is one flower in the picture (perhaps more) that I cannot identify. It is in the upper right and I have colored part of it in light blue, only to identify which one I'm talking about. Any help would be appreciated.

To the forum!
I think it's a stylized rose like the one in the lower left of the bouquet. Just from a different angle.

A few more guesses, just for grins...

It could also be a rose a sharon in the double form.
the only reason I think that is, the ragged(not smooth) edges.
Just a guess.
artists often combine flower.

My first thought was either a Rose or a Camellia.

I agree it could be either.
