Did this at 11x17 on my Huion GT220v2 tablet using Clip Studio Paint. Loving the use of textured brushes and used mainly two from Brian Allen's set. For the multiply shadow layer I used the Dry Brush from Ink and for laying down the colors use the Soft Grungy Brush from Paint. Used some Texture brushes for the foreground building DD is leaping off of. Nothing of note done with the background buildings as I wanted them to not take away from the focus.
