This is a sample, it is hard for me to do twice the same drawing, so 4 is a lot 

Will do my best to complete the first part today. 4' is ok so far. 

For my final project, I chose the Copperhead brush (I would never have guessed it at the beginning of the course):

I made another one today, with another reference photo that Gia has provided. I used Copperhead brush for the plant and Eaglehawk for the pot. It was a little bit more than 15', may be 20'

I added a paper texture at the end.
