You are bucking the trend using this approach with a digital camera where the practice seems to be to utilise full exposure to keep any noise to a minimum and then adjust levels or curves and vibrance/saturation in PP.
You have achieved what you set out to do but I think the result would have been better if it had been done with post processing assuming you have some software to do it. A bit of cropping around the flower would also help.
