Probably to make the mountains and the astronaut taller.

But yeah, mixing bittage=no.

First off, note that ripping is not received well on this forum, it just gets that way when you've got a lot of people who know how hard it is to work on something and then just have it filched. As artists, ripped art is a big thing. Look at it this way; how would you feel if someone took a game you worked hard on and then just put their own graphics without asking? Yeah.

Next, onto the graphics.

The graphics you actually made are ok, but they don't match the "stolen" mountains.The detail on the mountains just screams for craters and bumps and whatnot. The earth is not terrible, but the blur effect does not work.

You probably feel wronged, along the lines of "I just wanted to show a game, and I get this crap, what the hell!!", but try to see it from an art forum's viewpoint.

Being someone who sucks at run animations myself, I've studied some videos, and I think why this(the side view one) looks like power walking instead of running is because of the kick it has at the end. That's more for walking, not running. When running, your feet seldom go / but more < , if you know what I mean.

The arms also are more suited to walking. When running, your arms are usually at an angle, never spread out, because that could indicate being relaxed, and therefore better suited to walking.

And yes, I was running back and forth to the kitchen while typing this. 

How come only his right foot has the recoil part?
Coming along nicely.

Look away

I think what he means is you can make a mockup of anything, if you like. No one's really stopping you.

I have an idea for a Challenge; "Games you will never EVER get to see",
