Madness In Space Needs blood.
Why is this rated M? The earth looks good. And the stars have a nice effect on them. And I like the colour of the glass on the people's helmets. But Madness people feet don't hover. Only their hands do.
The moon is ok. When you drawing stuff like guns or hands, zoom in to it erase any slight errors or add more detail. I noticed on the guy on right, there is a rectangle on his back, with no colour. Because of the smoke below, I'll assume that it is a jetpack. I would have added colour to the jetpack.
Thats all from me. Bye.
