Classification suggestion for leaves: entire, lobed, and toothed leaves
Entire leaves : round/oval shaped with smooth edges
Lobed leaves: "classic" leaf shape with multiple lobes and indentations between them
Toothed leaves: sharp edges with many "teeth"

Implementation:

1. creating a data set by hand with the current drawing feature
   --> resulting training set for the NN will be close to images it will be applied to in the end, but dependent on manual entry
2. automate creation algorithmically: entire leaves represented as oval shapes, lobed leaves add 3-7 triangluar shapes to the oval, and toothed leaves add 8-20(?) smaller trangles on the ovals edge
   --> resulting training set may be more abstract and potentially less accuarte for the final use
