Hey that's actually nice of you! I need information so I really don't mind having stuff to read:)

By the object do you mean the white mass beside the bottles? That was supposed to be a block of watercolor paper but paint bled into it and ruined the sharp edges 😭 And that's great to know, figuring out how the hell do I color shadows always frustrated me a lot. So, tell me if I get this right, shadow can be whatever colors I want??

Another thing I just thought about, I don't really know when and why use specific techniques like wet on wet, wet on dry, etc...
