scale figures

I like that the images in this picture seem ghost -like, but still accurate at the same time. I also like the use of watercolor and that she put shadows with the figures. I think this image portrays the images well, without taking away from the architecture drawing. You can see more stuff here.
This image looks like the figures were added after the drawing. They are light, yet they demonstrate the scale. I tend to like lighter, less distracting figures. These figures also look like people which is nice. Go here for more.

What i like about these figures is that they show a lot of movement and gesture. The one in the striped shirt looks like it's laughing. I think if you can show movement in your figures it makes your drawing look more appealing. It also makes you want to be in that space because people look like they are having a good time. Link.
