I explored with two colour schemes and compositional methods for this image:

In the first colour test, I tried to stick to the colours in the actual image but I wasn’t getting very dynamic tones. I took your advice for the second image and skewed the houses a bit, much like how Frank Webb does, and used colours similar to his paintings that would give the overall painting more contrast.

I think I can work on shifting more hues with the second draft and being neater with the shapes so as to give the houses more structure. I think I can increase the saturation of the colours used as well to make the painting more vibrant. Do let me know what else I can do to achieve better tone and saturation overall. Thanks!
