Carmelite development 2 - black and white

I have been working a lot in black and white recently as I am trying out new processes and digital programs. I find it easier to work in black and white (tones) at first before experimenting with colour.

successes
- texture and depth of rocks as well as their suggestion of the water around them
- compositions using the sky to highlight the horizon
- use of scale and distance (although main character can become lost

things to think about
- black and white landscapes seem bleak
- do the more cartoon like characters match the landscape
- is black and white appropriate for a childrens book?
- can I demonstrate emotion effectively with characters
