Hi! Here is a shaded still life I drew and I have a lot of questions regarding it. The process: I first drew a composition, to get the proportions and relationships right. Then I found the horizion line and drew the objects in perspective. I established the midtones and put a lighter value in the background at first to not blow all of it off. Then I found the direction of the light and according to that I drew the shadows. Then I found the terminators, reflected light and occlusion areas. Then I painted the light areas and finally, the highlights. Questions: 1) Where the apple creates sort of a "darker spot" in the shadows of the cup next to it, is that an occlusion shadow? 2) Did I understand the direction of the light source? It seemed strange to me why it appears to be coming from different directions when I look at all the cast shadows. (I drew red lines into the reference to show what I mean). 3) Is the horizon line at the top of the upper cup? 4) The highlight in the reflection of the table is positioned as if we were looking at the cup from down below? Or how does the highlight work when it comes to reflections like mirrors etc. 5) What causes the value transition on the board in the background? Is it because when a plane is big enough, it gets darker as it moves further away from the light source? 6) Are there 2 light sources? The cast shadows indicate that there might? I realized that just after finishing the study. 7) And overall, am I doing this right? What can I improve? How? I apologize for this being so long but I want to make sure I really understand what I see. I will be very thankful for any answers and feedback. Thank you!
