Off camera flash flower

I am trying off camera flash and light modifiers, what do you think? Exposure, frame, crop?

I think it looks good .
Maybe just a little bit more room at the top not much.

background is a bit underexposed, is that how you intended it ?

I would have tried to avoid the diagonal on the lower right

also I would remove the dust spots

My sensor must be dirty, yes I intended for it to be underexposed in the background. Kind of a dramatic flower. lol

I like it. I think the colours work really well. I agree about the stem on the bottom right. I wish that wasn't there. Also some of the shadows cast by the flower a bit too strong. I think a diffuser could've softened those up.
