This is shit.
You have no sense of perspective. A simple code to have the character increase or decrease in size depending on it's distance from the vanishing point would have been a huge improvement. Also, you suggested that having the bushes there, which the character would move behind after a certain amount of walking, would create a sense of depth. It doesn't, as they're all on one flat layer. This is just 2D, there's no .5 about it.
