The Earth atmosphere is nice but the picture violates several of Nature's laws. The moon should be a thin crescent and you cannot have a shadow like this on the Earth. Since the sun is still partly under the horizon the earth in front of you should be in the shadow. In fact the Earth should be a thin horizontal crescent... And if it's the Earth, the moon and the sun should have about the same size (since you are much closer to the earth than to the moon):
