I would have had the same dilemma, it is a small flower against a big background, what to do? Well I think you did just fine, the colours are glorious, the blue shadow of the flower helps to isolate it to a degree, but the colours and texture of the background are part of the beauty of this image, and the overall effect is beautiful, so even if the flower is a little lost against the background who cares? As a study in colour and texture it is a very worthwhile artwork, and well worth the climb. It has that feelgood factor.

Life is very nice, but it has no shape. The object of art is actually to give it some, and to do it by every artifice possible - truer than the truth. - Jean Anouilh 1910-87
