Pelarganium botanical drawing

After I have been busy for a while with taking macro photos I undertook a new adventure: teaching online botanical drawing for beginners.

Just finished writing the text and drew sketches and drawings for the online course.
The content of the online course is 47 pages with more than 80 pictures and 34 excercises.

It was a huge challenge.
The drawing of the Pelarganium is placed on the last page of the course.
As always: very difficult to take a scan of this drawing like this, but here it is.
