Personally, as I'm a total beginner, I found the projects a bit more challenging than I first thought. I really liked drawing the hyacinth in fineliner and was quite happy with how it turned out, especially the flowers but not so much the bulb. However, I felt lost when I had to add watercolours, I wasn't sure how to go about adding the different colours around the flower bunch rather than in individual flower.
The daffodil came out a bit better, IMO; but the tulips seem to be missing some details. Still, it was fun to push my limits and practice painting flowers in different styles.
