I need to work on my backgrounds, so I wanted to make a rainy sketch of the metro buses here in Mexico City...
Process:
Linework...
A little bit of base color, the trees were a bit hit an miss, but ended up using a dot brush.
light highlights, and rain, another custom brush.
The girl was a mini sketch in itself...
Tons of gradients and reflections to finish the sketch.
Hope you liked it, stay dry !
