Hi, currently I'm working on the shading of flowers and I don't really know how can improve what I have ( screenshot attached). Currently I'm only using diffuse color (no specular) with a color ramp to use as an indexing table for the diffuse value ( mapping -1..1 to 0..1 ) and it's "ok" though it's not very visible. I've also modified the normals of the petals so they resemble the normals of a sphere to get a more uniform look (tought it also doesn't seem to make much difference).
I'm about to try out cook-torrance and see if it makes some difference. Also my model is very low poly due to having to instanciate a lot of the flowers, so it makes it a bit difficult to make something pretty and smooth.
Are there any known techniques for this kind of things ?

And this is the color gradient for the diffuse
