Improving Dawn of Light - Shading

[Vortigem]

Once again, I've picked up on my epic long struggle to develop Dawn of Light's GFX.

Currently, I am revamping the entire tile set I had been producing earlier, my current goal is to polish my shading technique so that it compliments my art style and use it then onward for a perfected tile set.

Below is an image showing the before and after development thus far, please respond with your thoughts & suggestions.
