Cliff castle with some concept sketches

I was about to go to sleep and had this idea pop in my head of a cliff with animal headed cylinders extending over the edge. After a few sketches I worked up this idea. I like it but got too mired in the messy middle phases. The values work desaturated though so I know they are good:) * If it looks good in black and white then the shadow to light balance is correct.

I wish the architecture was designed better - it is really bland and not to scale (windows are too big by far) but I didn't work on a detailed sketch so had to make it up as I went along. Next time I will definitely use real perspective and map out a tight sketch for architecture before painting.
