I see you use bounch flash. Besides bouunce, you can try side lighting with a reflector.
The problem is your exposure is slightly under for my liking.
Second is that you choosed the wrong background which happends to be your home wall.
Third is that your composition is all over. No define shots. You should concentrate on one part of the flowers instead of just shooting the overall subject.
As stated by the rest, WB needs to be adjusted. I am pretty sure this is not the colour of your real flowers. Plus the DOF which has been mentioned as well. DOF is very important when shooting close up subjects. This will help when u have too much busy things going on in your photo.
