Glad you enjoyed it! The storyboarding took about a month. (You can see a version of it in the behind the scenes video I linked in the description)

Thank you, I use a ton of squiggly lines, in fact pretty much the entire piece is made from using a small brush and smudge tool

For most of the painting I use a brush set up to work like acrylic painting and I use alt to sample colors from a pallet that I predetermine for each material/object in the image.
For the fire effects I first paint out the streaks in white, and then use the smudge tool to make them look a bit like fire. Then I copy that layer, blur it, and then adjust the color (in this case I darken the white and make it purple.) I take that layer and set it to hard light over the white which gives it the glowing look. I did pretty much the same thing for the embers.
I use a lot of lighting effects and gradient layers filtered over the image and masked out to give the depth and atmospheric prospective.

One of these days I will have to do a speed paint recording to show how it all works.

Thank you very much :D Yes Saitama was truly an inspiration on this piece. I wanted to capture his unpredictable destruction throughout this piece.
And i have included the link to my mid development in the description of this image, or have i done it wrong?
