Painting Treez

What decisions did these artists make? What similarities/differences between their decisions did you see?
The decisions the artists made we stuff like how they are going to draw the tree, stylistic approach, medium used, etc etc. The differences I saw were how the artists viewed the tree, and what their thoughts on it were ( and again, the medium used). Something I think they all had in common was theat they thought the tree to be grand.
How could you characterize their styles, and what impact does that have on you (an audience member)?
All four artists have very different styles. One was more of a post impressionist/architectural type, one was an impressionist (the one that used a palette knife), one used black and white only and the painting turned out looking cartoon-ish, and the last one made his super super detailed and realistic. Each style invokes a different emotion from the audience.
And, most importantly, how have they described their moves? Be specific.
First, each artist talked about the tree itself(what they see in the tree), then they described how they were going to reproduce it (techniques and such), they talked about the mediums they used. For all parts of their internal monologues, they backed up their thoughts with reasons.
