Practicing Composition with Flower Drawings

The images below focus on different composition options where solely working with my illustrations. Still considering and wanting to add text within my range, I have left appropriate spaces, however i certainly feel that the flowers are beautiful solo. On my iPad I played around with the different layout options, focusing on the sizes of the flowers and what colours worked best together.

Evidently here i have tested a few different backgrounds, and for me the most successsful are between a plain white / cream / ivory / ecru background, as well as the neutral sage green tones. The colours I dont favour so much are the tones of blues and pinks to sit behind the flowers - I think ill definitely be working towards as much of a natural colour palette as possible.
