Elements To Setting Up a Still Life

My young friend came to the market with a pocket of acorns. He was thinking theme before he got there. I think that is pretty good thinking. 
The market produce is certainly moving into the fall season and we went around looking for something that would speak to that theme.

I made suggestions as to what to consider as a good starting place for the still life, as in different kinds of contrasting elements, such as in warm/cool, light/dark and big/small. Shapes also will come into consideration. 

When David was setting up this still life we then have another bunch of design concepts to consider. Because he has a natural eye for this stuff it usually works out just right.

We were talking about our relationship, was I his mentor, teacher? I felt kind of funny having that kind of title but after looking up some definitions on mentor it seemed just fine. I try to give him some direction and a few lessons as we paint but it's just fun to have a painting companion. 

The market is a bit like trial by fire for someone and I keep telling him he is very brave to be out doing this. I found this market pretty busy but as I missed last week I was also pretty up for chatting with everyone. It was quite fun in fact. If I get into a mood or space that I have to complete something and to complete something that is good I'm in trouble from the get-go. Also I didn't set out the previous paintings as they can get some enquiries as to price and do I sale my work. I'm out there for other reasons and I have decided the market is not the best place to try and sell at. I also have been doing this for the past 4 years and nothing has sold while I've been there. Live and learn. Some of the comments have pushed buttons and that is not what I want either so best to avoid the whole issue of selling.
