Help regarding shadow/ reflection I had posted here earlier and received some useful tips. However, I have one concern that is still bothering me.

The shadow on this phase seems to be going from light to dark to light, along with a streak/ line of pink. Ideally, I would like this entire phase to be uniform or a gradual gradient. Maybe something like this:

is this the reflection from the sphere at the top and the plane down below? if so, how can i remove these reflections from interfering in the shadows. Could this be something completely different? I've kept the roughness of both the shapes quite high.
My new setup is:

Thank you in advance!
Both of your lights are very close to the ground. Try moving them up a bit, especially the point light.
You should also add a light on the other side of your object shining on the shadows. This light should be much softer and would soften up the shadows so they don't look so harsh.
There are lots of tutorials to help you with lighting out there. It might seem simple, but good lighting is much more complicated than you would imagine.
