Fitness Classes in the Park

Fitness Classes in the Park - student project

I have been practicing drawing the figures movement and dynamic energy for a commission. Can't get the form perfectly, but will keep trying! 

I would really appreciate some feedback, do you think I should focus more on drawing the figure form correctly? I don't feel I am understanding value correctly. I have watched lots of your class on understanding value which have definitely helped.Fitness Classes in the Park - image 1 - student projectFitness Classes in the Park - image 2 - student projectFitness Classes in the Park - image 3 - student projectFitness Classes in the Park - image 4 - student project
