I like the concept of creating floral abstracts explained in this class, and I used some acrilyc colors, watercolors, black pencil, polychromos colour pencils, black ink from the bottle, charcoal pencils, and ink pen. For my final project with violet and yellow colours, I used better quality of watercolor paper than for the practice,, and I feel it made the difference.

For pink-rose colors, I used black liquid ink from the bottle, and applied it with the tiny brush as that's what I had, but lines were uneven.  It is therefore that  on one of them I used ink pen which was easier to apply. 

When I tried blue colors, I used charcoal pencils, and I liked the look of it, however it is easy to smudge the lines if they are not fixed, which happened to me.
