So, what's been happening? I've gone a bit mad colouring in pictures using the vector tools available in Clip Studio (having decided that solid areas of shade look better than airbrushed tone).
I've also been doing a lot of silly cartoon pics recently, most of them coloured-in versions of old pictures that have been gathering dust on my computer.
The tortoise and hare pictures are still ongoing - most of the work is colouring in the characters and producing the backgrounds - fortunately there are some useful tutorials online on how to digitally paint trees, clouds and other background elements.
