Despite the time constraints, I do suggest practice for the sake of growth and personal creativity. Creating art only for money is hard on the soul. Revise your schedule to include 2-4 hours of undisturbed practice weekly, if at all possible. The Mind should be able to wander as well. This is to decrease personal stress, as the stress of stifling creativity builds up in your brain and veins.

The NSFW piece you did demonstrates a stable foundation in composition, color, value, and other foundations. You did well in it, and of course should continue to make those types of things, if it makes you happy. Much appreciated for bringing your work to us.

Note: The English is of acceptable, not poor quality. You are doing well and will adapt to more precise details with time! Go easy on yourself ^^

Thank you so much for your suggestion! ^^
