Here's the full timelapse! (no audio)
rough thought process:
start - 00:25: I'm just doodling, trying to familiarize myself with the sketching brush
00:26-00:28: I do a quick line study of Waterhouse's Lamia and I think 'hold oN-'
00:29-02:25: rough sketch and lines
02:26-02:55: underpainting
02:56-03:55: on a separate layer (still under the line layer) I start putting down more colors and start working out forms
03:56-08:00: I start working on yet another layer on top of the line layer and work on the shapes
08:01-10:00: their faces really bit me this time around and I did some trace-over studies in another document which I copied into this one (the white lines flashing up at around 08:05) and I eventually re-lined Merlin's profile at 08:12. It was Arthur's turn at around 09:20.
I spend the rest of the time fixing Merlin's leg and adding detail to the clothing, trying out different background solutions. Plus, the skulls keep popping back in since I really wanted to add them but I wasn't happy with how barren it would have made the piece look.
At around 19:00 I import the sun and moon from my Wishing morgwen piece because I liked the look of the sun and I wanted to imitate it but it didn't work 😆 I instead proceed to make the sun an egg and don't notice until much later!
19:50: I add a multiply layer to add shadows
20:26: I start adding non-descript greenery which later morphs into a flower bed (and a nice ground to plant some moss-overgrown skulls)
28:00: I finally notice that the circle shape isn't a circle and I add some finishing touches.
