What Do You Mean by Map Execution?

So whenever I submit a map out here in the DW community, you say something about "execution". Like my Dead Anomaly

Interesting concept, bad execution

What do you all mean by this?

Basically means that the idea/theme behind the map is good, but the actual map itself is shit, be it through bad gameplay, thing placement or general layout. Maybe even all three.

I've never played your maps, but the concept of bad execution is pretty much what BaronOfStuff said so I second his statement.

Execution
= rendition
= implementation
= the actual interpretation of your idea
= how well you actually made the map
= how good the map really turns out for the players

"Interesting concept, bad execution" means that you had worked with a nice mapping idea, but the result turns out badly anyway, because (in the view of the reviewer) the quality is spoiled by flaws - in gameplay, particular design, visuals or anything.
