sheep blue..thank you. I see exactly what you are saying I definitely missed the shadows. The photo is slightly overexposed so the highlights on the lemon are very bright, but in the painting they could definitely use brightening.
it is interesting looking at it through a camera lens. I totally missed the shadows thrown by the grapes until I did.
I plan on doing a different one every time I paint, rather than reworking that one.
It is frustrating as I know that I could do a lot better with acrylics, but I need to push myself in this direction.
Honestly, I find that painting from a picture is generally easier, although every teacher I ever had in art school always said not to do that lol.
It'll be very cool to see a series of paintings from your first to your last (or ongoing!). It'll be a great display of your progression with the medium. My hats off to you, I only dabbled with oils once in high school and generally made a giant mess of it. You're light-years ahead of me there.
I agree with what thisbird said too, about looking at shadows and light and color rather in sets of shapes. That goes for coloring too. You'll be surprised how much color you can find in shadows with the reflections of certain colors influencing the objects around it. I learned this especially when doing still lifes with transparent and shiny objects - what a pain!
