the colors and shading and highlights are all drawn fairly well but the clouds structure is a bit unrealistic. instead of the long lines, smaller puffs would serve for a more real look. and with your blending, it could be smoother, a good trick is going low opacity and messing with the color picker and using different shades of colors for depth.
Thank you for the review and for the tips, i will surely upload better content as I get better at this :p
