This sketch was drawn with the reference photo provided by Alice Lim.

Tinderbox is a default Procreate brush that's great for sketching. The edges and strokes are both textured. The brush can be tilted to created broad textured strokes to quickly cover large areas. This is much better than filling areas with solid colours.

If you don't like the textured edges, you can go into the brush settings -> Shape -> reduce Scatter to 0%.

Here's a draft of the earlier sketch drawn with the modified Tinderbox brush. I like this better than the coloured sketch. For some reason, I always sketch looser when I'm not recording my sketching process.

Anyway, if you want to learn about urban sketching with Procreate, check out my online art courses.
