I did a quick paintover!
What I mainly wanted to touch upon is that composition and the poses.
In the original piece, they feel very on top of each other and there's a lot of pink hair flowing everywhere, making it very difficult to discern what's going on. So I really wanted to separate them, giving them individual silhouettes that stand out more on their own and together in the composition. I also had some trouble seeing how the perspective worked in the original piece, so I moved the camera way up high almost looking down on them. giving it that feeling of an album cover.
Really think about those forms in space and how to turn them they way you want.
I also wanted to give feedback on lighting, but felt it was too much information for one paintover. But! Think about your light source, what's the light hitting. And don't be afraid to go dark with your shadows, giving you a wider range of values to play with!
Hope that helps! Great work, keep going!
