Good piece, strong sense of the ominous and the unknown. After the detailing of the grass and the beautiful semi-parchment sky, I do wish that there were a little more to the amorphous blobs that indicated effort or polish, though I appreciate that having them be shapeless masses with no detailing except for two points for eyes may have been a stylistic choice.
I really do appreciate the color palette, as limited as it is, because it fits the picture nicely. I think in the future just make sure that different parts of the piece match; the more I look at it, the more I feel as if the grass and the sky go together, but there is so little done with the blobs that they seem almost cartoony in comparison.
