Thank you so much for your nice comment and all your efforts you had with your thoughtful critique! Don't worry, this is the first one I ever got and I never dared to write one yet! So thank you again! Now to your question about the light sources: I got this question already once in the long line of comments rather early. So I simply post my answer here again. The question of this deviant artist was concerning the light between the "apple box" and the wooden box, but I think my reply would answer your question as well. "The light really came through between the vase and the wooden box, it gave the board this nice blue glow I tried to save in my painting. On the other hand my kitchen has three tall windows, two in a line (one right to the one you are just looking at and a thrid window on the left in a rect angle to those. In addition to that the open part of the window reflected some light which were a little enlightening parts to the right again (The sun was shining from the right side). So the sum of these windows, the reflection and the fact that also much light comes from above, might have caused what was kind of confusing you. This is really painted at the object and not by fantasy. I always do so, I might sometimes save moments in a photo first to keep the situation right in my mind. Flowers can fade and certain sun light disappears after a time. And then I take this as "model" for my painting to be sure that all perspective, proportions (as far as not intentionally altered) and the lighting are okay."
