I like people that seek for opinions and make use of the ones they see best fit. And that makes a wise person. (I will be enhancing the clouds with white gouache and strengthening the shadows of the balloons folds) nice one.
Weldon with the painting; so far, you are doing a nice job.
Thank you @peks, colbalt blue, which is a dark blue, not the red hue, I'll end up with a purple sky. The blue will add depth to the sky. I find working with my commenters add extra spice to my paintings.
