Aiman, you have a very keen eye for isolating subjects of smaller sizes. You have done very well here but a tripod would have permitted you to use a smaller aperture to render more of the lovely flower sharper. Another way is to shift your angle to get more of the flower as parallel to the film plane as possible, to capitalize on the DOF. Using your DOF Preview would help too but its takes lots of getting use to. Great lighting too! Lets see more of your photos!
Out of focus and your highlights are blown out, but I realize you're limited when hand holding your camera with close up filters (I assume that's what the +1 & +3 is about). I find the diagonal stick distracting. If you can, try this again with a tripod and smaller aperture. Also, clear the clutter and bracket your exposure.
Hmmm...lots of great things to say about this one. Colorful, simple, and I love how you've included the little stick to diagonally divide the picture. Just a couple of concerns...I would've composed it to have the end of the stick leaving the photograph...something to help lead my eyes completely out the other side of the picture. More DOF would've probably done this picture more just as well. However, aside from these two things, it's a very appealing image. A real eye-grabber. Good job! :)
