Heya!
Not an expert on distillation studies but I believe one of the main points of distillation study is to unite smaller, singular shapes into bigger shapes and make said shapes appealing (shape design). While there are a lot of such united groups in your studies (Great job on those btw!) I think there are also a lot of those wild, separated small shapes that really kind of ruin the point a bit. I think it's best to sacrifice shapes like that in sake of better overall design, you can add those in later stages when the shading applies softly or at any point later really. If you absolutely have to include such separated shap during distillation phase, then I believe it's best to work on its' design (for instance, if it is a shadow shape on an arm - a generally cylindrical body part - then it should convey that information as well).
Hope this helps, good luck!
