I shared about it initially here. I know it still needs more work like darkening some parts and doing more contrast but nothing in my current skill set can make any difference knowing that fact.
I'd be reviewing more values and depth as the target. Going to limit most of my practice to greyscale but will still do colors for experimental random arts. The objective wasn't to go nitty gritty detailed over this but just gauge what I can do so far.
