Decisions On The Chaise Rug

I’ve been steadily plodding away at this rug and now have to decide about a couple of things.
Firstly, the blue in the centre of the larger floral motifs is from an old cardigan (meaning it’s not dyed wool and has a different cast) and the colour seems too strong. I might change that and use the same as the other flowers. Yes...
Secondly, maybe the pink and probably the oranges in the larger motif doesn’t feel right. Either or. I’m not sure whether to bring the pumpkin into them? Mmm... Or is it just the lighter, candy orange one (nearest in pic above)?
Sitting here on the verandah on this gorgeous, mild winters’ day, I see there’s a clash that offends me. I’m just pondering out loud and inviting you to suffer along with me.

I don’t care what anyone says, I like the green.

You can see I’ve made a dogs-breakfast with my scribbling in figuring out the background. I tried adding a swathe sort of thing in subtle but different colours, which looked wrong... then I added raised spots with the background colour. They looked amazing but not for here. It was way too much and it’s already too colourful for the poor One True. Good idea for another rug... just raised spots in one colour. Like those moss rugs.
So I’m stumbling through the fog of an idea to use only background shades to suggest foliage, inter dispersed with dots that are not raised (I’ve started but the floor really really really needs vacuuming and my hand hurts).
Or, just work in a direction, with lines flowing out as the now defunct swathes suggested.
Excuse me for boring you to tears, and please, feel free to butt in. 
But you might be pleased to know I’ve decided stuff just in talking it through. Thanks.
