When you added all the white highlights your picture will look this. Save your work.

Now we going add a few darker spots so the petals will look more separately instead of glued together. Use color #A14F5B to make contours around some of the petals. Go back to your retouch tool and use these settings. We are not going to smudge this time but we use DARKEN RGB.

If you have trouble seeing your petal selection lines you lower the opacity of your petal layer to app. 50. Don't forget to raise it back to 100 when your done with the dark contours. Make sure you draw the contours on the petal layer !

When you done this save your painting and take a break. Mouse needs rest too ;)

Ok ready to proceed ?
Go to Image - Canvas size and apply these settings. It's big I know but we will need lots of room to move around. We always can crop off the excess canvas later.

Add a new raster layer name it leaves and click on your preset tool. This is going to be tricky for psp beginners but i'll try to explain it as easy as possible. Draw a triangle with these settings

You will see a new vector layer above your leaves layer but that's ok. Now we got a triangle and we want to make it look like a leaf. Click on "Object selector" next to the preset tool and you will see your triangle selected. Rightclick and select from that menu "Node edit". Pull your triangle to either to the left or the right a little (img 1)

then rightclick on the rightlower corner of your triangle and click on "node type" and select "curve after". Then pull the line outside till you get a curved side (img 2)

Deselect by ctrl-Q you leaf looks like this

Make as many leafs as you want for your picture and arrange them on your flowerpicture. Make sure the end of the leafs are partly covered by the flowers once you move you layer under the flowerpetal layer. Once you made all the leafs select them and rightclick it will ask you to defloat on the nearest layer click yes and you will have the leaves on your leafslayer. This is how it should look.

Save your work !
