I did take out quite a lot of the green, and put in some pink - to try to work it in more naturally.
The difference between the top and bottom parts is quite clear with the change in stitch direction.

Looking at the scan makes me wonder if I need to do some work on the at that part of the petal - where the pink/cream/green/dark green mix starts. There's a curved light line that seems to be standing out a lot.

I'm also tempted to add some more dark edge on the top part - but that's not the pattern and I know that I'm a sucker for the darker colours. I'll see how it looks with the flower more completed. I think the dark edging on the bottom part has worked beautifully, but it looks so patchwork-y on the top part.

I also put in a split stitch line of two different pinks between the top petal and this right one, to make the delineation a bit clearer. It is a bit clearer in the original than the scan because you can see the texture of the stitches, as well as the colours.

So these are all small design decisions to be made later when I see what the flower looks like as a whole.

I think this sort of process/thinking is shown by how the fold over at the top of the top petal looks a lot more natural even with just the marking up on the left petal next to it. Giving it some company makes it look like it belongs.

Onto the back petal - it's all marked up. It's in more brownish sort of colours, which will tie into the centre. Yummy - more new colours to work with.
