Good afternoon,
My name is Alizee Zimmermann and I am an enthusiastic and prolific artist and have a number of original pages that are very much in the style you are looking for. I hail from the beautiful Turks and Caicos Islands in the British West Indies and the natural surrounding and marine life there are very much an inspiration for my artwork. I have recently relocated to The Netherlands and have been using a lot of my new-found free time to draw.
Some of the books I have looked at are 'The Secret Garden' and 'Enchanted Forest' by Johanna Basford, 'The Mindfulness Colouring Book' by Emma Farrarons as well as the Dream Catcher books.
I would be very much interested in finding out more about the project, for example what size paper will the book be printed on and whether there will be a general theme to the compilation or if it can contain a variety of themes e.g birds, marine life, trees etc.
If you have any questions or would like me to send an example please feel free to message me. I look forward to hearing from you, have a great day!
Alizee
