Not photorealist

thanks for the nice comments. The third image was expected to take a whole A1 page for the presentation of the challenge. So I very appreciate your opinion. I prefer to produce some non realistic picture for architectural challenge to highlight the concept of the project. And it takes less times to finalise them. Each of these pictures was produce in less than 3 days.

very nice. I really like the tones and linework for all of them. My only comment would be that for the third image, the green is overpowering, maybe cropping it down to read more horizontal would help? Great work.
