3 layered crochet flowers - Tutorial

For a long time I've tried to find appropriate pattern for 3-layered crochet flowers. I know the pattern for Irish rose, but I don't like the hole between the petals and base made by the other color yarn, when the petals are created.
So, I did this pattern from "mind" and it's close on that what I'm looking for... Here it is:
First, I worked with 100% cotton yarn from St. George, Serbia and 3 mm hook. I used those stitches in US terms:

SL ST: insert hook, yarn over, pull the loop back through the stitch, then through the loop on your hook.

SC: insert hook, yarn over, pull the loop back through the stitch (two loops on hook), yarn over and pull through both loops on hook.

HDC: yarn over, insert hook, yarn over, pull the loop back through the stitch (three loops on hook), yarn over and pull through all three loops on hook.

DC: yarn over, insert hook, yarn over, pull the loop back through the stitch (three loops on hook), yarn over and pull through two loops on hook (two loops left on hook), yarn over and pull through remaining two loops.

TC: yarn over, yarn over, insert hook, yarn over, pull the loop through the stitch (four loops on hook), yarn over and pull through two loops on hook ( three loops left on hook), yarn over and pull throw two loops on hook ( two loops left on hook), yarn over and pull throw last two loops on hook.

Start with magic ring and make 12 DC in it. Join the last DC with first DC with SL ST. The ring is closed and the base is made:If you want you can change the color or continue with the same, so the second layered petals will be in the same color like the base. I'll continue with the same color. Now, we are making the second layered petals.
*Make 4 chains, skip the next st and join in the next st with SC* repeat 5 more times. The last ch join with SL ST with first made ch:


Now, we are working the petals in every chain-4 space ( there should be 6 chain-4 spaces) in this order: SC,HDC,DC,DC,TRC,DC,DC,HDC,SC
You should have a flower like this:
Now, we are working the first layered petals in the skipped chains. Insert the yarn in second color:and work the next stiches: SC,HDC,DC,DC,HDC,SC
The last SC join with first SC with SL ST and fasten off.
Now it's time for the last third layer petals. Insert the hook throw the one of the pillar from the second layer petals. See the picture below:

Now, pull the yarn in third or fourth color

Make 5 ch and join with SC on the next pillar. Repeat 5 more times.
You should have like this:
Now work in every ch-5 space in this order:SC,HDC,DC,TRC,TRC,TRC,TRC,DC,HDC,SC

The last SC join with first made SC with SL ST.
And, the flower is ready:
And there are more flowers:
I hope you'll enjoy making those cute flowers!
