I really liked the first entry, but I'm not sure I like the update.
The ramp looks too steep, it's almost vertical on the left side, and the angle's different on the right side. It should also probably have some shading on its face, since it's not completely vertical.
I don't like the grass because there's too much focus being placed on the individual blades. I'd like to see it shaded more in clumps than blades.
I like the outline of the tree, except that one two-pronged wimpy root on the right between the other two roots.
Keep it oop! You're using the colors well.
