Finally, these are my final submissions.

Turn table animation. Next step for me is posing the character and facial expressions, stay tuned.

Made some more edits to the cape 'S' logo. Here is the UV texture edited in Photoshop.

A quick video to show the current progress, I might tweak the cape Superman logo at the back a bit more.

A few more tweaks are needed on the boots, as you can see part of the skin is showing on the boots.

I made more iterations this time to the cape. Thanks to reallusion for the cape downloaded from the asset store. Made a few adjustments to the cape using Photoshop.

I have more to go to refine further, but here is a screen recording of what I have so far.

Next is the hair. I wanted to go with slightly short hair, unlike what's been used in other depictions. I also converted the hair to the digital hair shader for a more realistic look.
