what type of tulip is that...for me I would have bumped you up 2/3 points if the whole tulip bud had been in super sharp focus...it's a little soft in that department (JMO)...I love your colors and composition...just wish it was razor sharp...
I love these type of tulips! Make for pretty pictures. A better background would help you - angle to get some more of the flowers in the background. You could increase the contrast too.
