Drawing Leaves and Flowers Structure

Mimusops elengi is a medium-sized evergreen tree found in tropical forests in South Asia, Southeast Asia and northern Australia. This trees give thick shade and flowers emit fragrance. I plant this tree in front of my house.
And here are some sketches of its leaves and one tiny flower:



For the flower, I choose Hibiscus, because I can find it easily in the park next to my house. But the flowers couldn't stand for more than 3 minutes. It kept on bending down and down. So I put a paper stick to help it stand up longer, as it act as a strong stem for the flower haha...
I dissect one of the flower and take some photos of it as soon as I can, competing with the speed of the flower wilt process. The photos becomes my resource in adding the details.

Drawing Nature, Science and Culture: Natural History Illustration

I'm joining this open online course from edX right now:


Drawing natural objects is a kind of art that I like to do in my spare time. It looks like a meditation by observing the details of the objects, absorb its energy and enjoy its beauty. There's no exactly same objects. Each has its own unique appearance.

And this morning, sadly I missed the first drawing submission to be assessed :(
It's my fault that I didn't pay attention to the deadline and note it in my calendar among my zillion to-do-list. Oh well.... I realized about 3 hours after they closed the submission :'(
Here what I drew for the (missed) first drawing submission:
