A limited palette study(Project townscapes)

I am going to use my aerial perspective exercise to practice this exercise for developing colour.

I used three colours of conte sticks which are black, brown and sanguine.

 

Overall i am quite pleased with the result as the dark colour gives me the outlines of the buildings while the light colours give the shading of the interiors. My only issues is as before that I did not get the perspective correct on some parts of the building.
