It looks ok to me. I think in a stylized approach with a lot of other elements that use the same general methods there isn't any major flaw or design issue. If you are going for something more natural feeling that reads better...
You could push your contrasts to help the red tones separate themselves. Your darkest colors are up front and your back row is using mostly highlight colors. This feels a little off depending on what you were going for with lighting and the actual bloom design. It seems as though the inside of the bloom is orange/yellow while the outside edges and undersides of the petals are pink/red.
Unless all those flowers in the back are pointed at a diagonal angle towards the viewer it feels like a little too much orange and yellow up there.
Your original version kept the individual flowers more separated and allowed them to stand apart and represent what they were.
The newer version presses them together like they are competing for space. Even the most dense flowering plants rarely flower this compressed together in one mass atop a plant. They tend to have a lot more height variations , diverse angling, and with greenery between them.
Most plants are capable of self-pollinating and they keep their blooms more spread out and angled away from one another to avoid that in nature.
