I was so excited after watching your first few videos I had to start my project before even finishing the class haha! I made my illustration & pattern in Photoshop. Here is my process from start to finish! Hope you like it! :)
I started with some very rough sketches & cleaned them up to create the outlines of my flowers... trying to make sure I closed all the little gaps so I could colour everything in easily! Thanks for the tip!

I picked my colours & cleaned up all the edges (and also, finished watching the rest of the videos lolol):


Added the shading (which I found to be the hardest part. Any suggestions on Photoshop brushes that blend well?) and background colour:

And finally created my pattern! YAY!

I loved this class! Anna, you are a very inspiring artist! Thanks for sharing your knowledge!
