Process of Mischief in the Garden

I don't get to see your streams often (I think I only personally attended one or two), so seeing this visual tutorial is very nice to see.   That also reminds me that I should try out/work on this thing called "colored line art."  That and working with soft/air brushes for more subtle shading. 

What happened to the background between the one you started to have in the middle compared to the end product?  Did you mostly just lower the opacity a lot and then add a few things in there?

Thank you for visually showing off your process!  Just by looking at this,  I think I have a couple of ideas now I would like to experiment with ....whenever I have the time.
