This second one is so much better than your first. Just look at that pistil - You tapered it and it is much thinner - Impressive!
There is no reason why you can't use the Wilton stamens. You can cut down if you think they are too long. You have to admit, it's much quicker :).
If you go with this color, which is more intense than the last one, try keeping your color heavier up the middle of the petal and sweep it outward to the stop point so you still have your white edge. More of a blending motion towards the edge. You will find the look of the petals will take on a more delicate appearance. If you don't have extra petals to play with, draw a petal on computer paper and play with your dust. You know you can always use food writers for the dots if you didn't want to paint them.
You should be very pleased!
PS I know this is for a cake you are doing now but maybe the down the road when you get more wires, you can play with the gum paste or even Twiddling to achieve the look of the stamens you wanted.
