Nice nuances! It all adds to the interest of the piece in your style.
What resolution are you working at? I would think now that you're getting this good you might be thinking about sharpening up the image and looking at how blurring works for you or against you. I'm just asking about resolution in case you want to get into printing large where the details get magnified.
I would suggest that you keep posting on the internet with lower resolution so people don't steal and print your work without your consent. That way you would have proof that yours is the original.
Well, you seem to have all the other aspects of doing these working very well. It's just that I'm noticing some things getting blurred with adjacent bits not. So it's just something to keep in mind as you approach perfecting your skill.
This is really terrific. Great job.
