Exposure wise It is fine, you are creating a mood and it should be to taste. I like it !!!
Composition wise might suggest some changes. Would like to see the top also tight like the bottom? If not then having more room at the bottom sort of to match the top? Particularly like the precise dof on the center flower. Texture is also appealing !!! Big Congrats on this one and love the thinking !!!!!
Alberto,
Congratulations...I like it the way it is. Remember, that photography is an art form that is subjective. There are rules to follow and composition and exposure guide lines that are in place. But remember that "beauty is in the eye of the beholder" Now that being said, You did great...conrats...:D I cropped it from the top like Mr. Al suggested and it works very well. Try it that way and see if you like it...:cool: I like the center focal point and the good depth of field. The soft hues on the roses is very pleasing; it gives them a soft warm glow...:D:)
Alberto, that cropped image is simply stunning. The main flower now is really the centre of attention despite (or because of) being moved from the centre of the frame! The mood is magnificent.
