Pastel Sketch and Cone Flower Painting

The top picture is the pastel sketch I worked from. I originally tried painting the intense yellow and greens I had in the sketch, but felt the painting was screaming at me. Sometimes I find it hard to work large from such a small sketch. I had to improvise too much in the painting and therefore I am not happy with how the painting is going. Any suggestions?

Another finished in the dried flower series. I haven't had much time to paint lately. My daughter just gave birth to preemie twin boys named Cole and Jack. The boys are doing really well for such little guys ( 32 weeks). So I spend time with my daughter at the hospital until the boys can come home. I am in the process though of squeezing in time for a sketch on a new canvas, so I can start that painting. Not sure if I am liking the blue centers on the two flowers to the left...should they be more purple or toned down perhaps?
