You've all heard of artists who make studies and sketches in the field and then retreat to the studio to use them as the basis for a proper painting. Having just spent 2 1/2 hours painting the figure from life, I hope you saved at least one of the sketches you made. It can serve as the inspiration for a more refined version of the pose.
First, put away the timer. You can take all the time you need, making sure you're pleased with the proportions, the colors, and the values. You can introduce more soft edges, or fewer, as the case may be. You can try out some surprising colors, either in another study or directly on the new painting.
By all means use good paper for this project, and remember, it is not imperative that you get the drawing exactly right on the first layer. there will be later opportunities to adjust and improve the shapes.
Here are some colorful paintings gathered from the web to give you some ideas. I'm not suggesting that you copy any of these. Use your work from Wednesday for the pose, and the images here as encouragement to take some risks. Have fun
