Coloring pages for play

I am looking for an assistant to create coloring pages for the mobile game "Coloring by Numbers".
Only black outlines without color.

Main theme: Plants.
You can add birds, insects, butterflies, objects.
The main thing is to match my style.
Approximately 10 works per month. Suitable as a part-time job.
Interested in long-term cooperation (while I am working alone).

If you have experience in this type of work and can show examples, then no test is needed. If you do not have such experience, a test task will be provided, which, if well executed, will become your first completed work.
