The Invasion

Hello everyone,
I hope you had a great MLK Day long weekend.
As for me, it was quite productive. I managed to finish two of my concepts that I started last month. Well, technically it is one concept but with different moods. After I finished the first concept, I wanted to do a snowy version. It was a lot of fun to work on it.
They are parts of my alien invasion series of visual developments called "The Last of Them" that tells the stories of the wars between a race of alien and the Earth United Nations.
"These creatures suddenly appeared from nowhere. After decades of wars, the human race stood on the brink of extinction. However, we will never stop fighting until the last of them dies."
Cheers!
