The Earth would cover the Sun completely during an eclipse viewed from the Moon. This is why a lunar eclipse lasts longer than a solar one, where the Moon covers the Sun as viewed from the Earth.

However, this picture can still be real. The sun's disk appears smaller than the disk of the Earth. Refraction of sunlight in the atmosphere would ring the entire Earth in light. This diamond ring effect is due to the Sun being to one side.

Pic is certainly plausible.
