Okay! Whew! Here I go!
First off, I really love the colors and "knifestrokes" here. The colors for the fall leaves, despite their seeming random placements, are beautifully aligned in a way that they create a nice gradation, which I find very pleasing to look at. If this was intentional, I would like to applaud you for your color usage. Also, I find the little touches of blue amongst the trees and the blue road to be appropriate and refreshing due to the overwhelming reddish and greenish tones.
Secondly, I personally was quite curious about and surprised about this painting being done with a palette knife, but it did explain the clean and smooth texture of each of the strokes. I think that was very unique and original of you to do so.
I love fall, and I really felt like going on a walk in the park to do some leaf peeping when the leaves change color here.
I do have one negative to point out, though it's really just me being nitpicky. I expected this piece to be predominantly red due to its title:"Red Fall 1," (I'll be waiting for the 2) but I don't think there's enough red in this painting for the title to be "Red Fall 1."
Nevertheless, this is a beautiful painting! Great work overall!
