Beautifully explained! I wish I'd had this type of instruction when I was in med school! Thanks!

@Marco Bucci I have a question about merging layers together that are in different modes in Procreate, please. When I tried merging the layers together that were in different modes (in the later half of the Procreate Owl demo) I found that I ended up with strange results- the colours changed. Marco, how do you merge those layers and retain their effects, please? I'm a Procreate user, with experience in traditiional oil. I wanted to be able to experiment with colours and composition - without the expense or mess! Thank you-- I really enjoyed learning your approach.

Thanks for the brush set-- great selection, very responsive in Procreate.

I need help. I’m having trouble with values, compositions and plane changes. I understand the anatomy but shading and separating my lights from my shadows to enhance the forms under the surface is very challenging for me. 😩😩😩😩 I’m super confused when it comes to that.

good evening Dorian- you're coming through clearly.

What would you say in a self-critique of this drawing at this point?

Thank you very much- the philosophy discussion was equally as interesting as the artistic demonstration and technical points.

would you please discuss your concept of shapes further- could you show us examples of the shapes you have chosen, rather than where you would simply "copy" the picture. What is the difference? thanks.
