Pick the Direct Selection Tool (A), click on the C point, hold down the Shift key and click on the D point to select both these points (C and D). Now grab the Convert Anchor Point Tool (Shift + C) and click on point B, then drag it to the right until our shape looks like the fifth image shown. Now grab the Direct Selection Tool, click on the B' point (the B' point coincides with the B point). Now grab the Direct Selection Tool and click on the A' point (the A' point coincides with the A point).
Now we go to Object > Show All (Command + Alt + 3) to show two shapes ("right_shape" and "left_shape") again.
We also draw veins for the "lotus_petal_stroke_2," similar to the way of drawing shown above. Continue drawing veins for the "lotus_petal_stroke_3" shape, similar to the method shown above.
Follow these steps as shown above, you'll need to draw lots of lotus petals with different shapes. Continue using the Selection Tool (V) to move the petals of "Group_III" into position as shown.
Finally, move the two petals of "Group_V" into position as shown in the first picture below.
After the veins are finished, use the Selection Tool (V) to select all of the veins and set the Opacity to 15%. We'll use some basic tools (Ellipse, Direct Selection, Pencil, and more) to draw lotus petals and leaves.
Now click on the "Remove selected anchor points" icon in the Properties Bar to remove these points. Continue to use the Convert Anchor Point Tool to drag two handles of point B, follow the direction shown.

Pick the Selection Tool, hold down the Alt key, click on the "lotus_petal_stroke_1" shape, and drag it to a new position.
Pick the Ellipse Tool (with a Fill of None, Stroke Color as Black, and 1 pt Stroke Size) and draw an ellipse shape. Hold down the Alt key, hover over handle 1 (a plus sign should show up), then click and drag it down as shown in the fifth image. Now, we'll draw the remaining half of the lotus petal, use the same method as we did in Step 2. First, we'll hide two shapes ("right_shape" and "left_shape") to color the remaining shapes easier. Use the Selection Tool to select the thinner shape, then go to Object > Hide > Selection (Command +3) to hide this shape. Use the Pen tool (with a fill of None, Stroke color of #EC008C, and a 0,5 pt Stroke size) to draw a curved line from A to B, as in Step 1.
To work easier, we need to hide the two thinner shapes (Use the Selection Tool select both of shapes and go to Object > Hide > Selection or Command + 3). Now select both petals using the Selection Tool and click on the first petal, while holding down Shift key and click on the second petal. Use the Pen Tool (P) (with a Fill of None, Stroke Color set to Yellow Orange, and Stroke Weight of 1 px) to draw an object as shown. Grab the Ellipse Tool (L) (Fill of None, Stroke Color as Black, and 1 pt Stroke Size) and draw an ellipse shape. Continue to use the Direct Selection Tool, now click on the A point and click on the "Convert selected anchor points to corner" icon in Properties Bar. Next, use the Direct Selection Tool and click on point C, while holding down the Shift key, then click on the point D to select both points (C and D). To do this, use the Selection Tool to select two shapes, then go to Object > Hide > Selection (Command + 3).

We also create meshes over "right_shape" and "left_shape," then add color to the mesh points.
Now right-click and select Arrange > Send To Back in context menu to send the two petals behind all the others. Then click on the "Remove selected anchor points" icon in the Properties Bar to remove both points (C and D).
Hold down the Alt key again, hover over handle 3, then click and drag it up, as shown in the fifth image. Next, grab the Selection Tool (V) to select object that A, go to menu Edit > Copy (Command + C), then go to menu Edit > Paste in Front (Command + F).
