It's a nice flower. It should be sharper; the center is focused but none else. There's a blue outline on the flower also-- that's somewhat distracting. And, too, a bit of the flower is cut off at the top. The black background does set it off well, however, and I detect a bit of color that seems to be from another flower-- that's nice.
I in no way intend to degrade your effort to capture what I'm certain was lovely; I only hope to encourage you in improvement. Keep up the good work and it'll get better!
"For the love of Christ constraineth us; because we thus judge, that if One died for all, then were all dead: and that He died for all, that they which live should not henceforth live unto themselves, but unto Him which died for them, and rose again." II Corinthians 5:14-15, KJB
