Go right ahead... I mean, all you need is enough land to do it... Actually I imagine that you would need quite a bit of land in order to build a face
big enough to see from space....
Now, if you were somehow able to acquire that much land, the question becomes what material would you use to build it? I imagine that you would want
this face to last as long as possible... So that any intelligent civilization could see it and know there was/is an intelligent civilization on
earth...
In order for it to last a long time we would have to take the environment we build it in, into account. For example, if it rains a lot where it was
built, dirt would not work because it would be washed away...
Now also keep in mind if the idea is to show any intelligent civilizations that may happen to stop by, that there is on here on earth, there are
already tons of things on earth that would let those aliens know intelligent life exists/existed.
You can see the great wall of china from space, and then there are the many sky scrapers that would hang around for quite some time... Mt Rushmore...
etc...
All that said, if you can do it, I say great!
