It's your hack and all and it's your decision whether or not you want to include the decoration in, but I'll have to echo what others have said in this thread: It doesn't look good in the slightest bit. I'd just like to inform you that visual messes like that will only lower the quality of gameplay because it'll only distract the player from what'S going on. Not only that, but it is not a good cover-up for all the other poor choices in aesthetics, like the graphics or the palette.
Now, if it's intended to be a factory, first of all, all those wall tiles spammed like that aren't enough to make it look like a factory, but that's not all why I'm here for. You should definitely replace the background with one that is fuller, as the clouds against a black canvas isn't doing you much favors. Industrial things such as girders and the like should be added to make it more complete. Maybe also add some hills or whatnot into the background, just to take up a bit more empty space? I'm assuming your willing to draw all this. If not, a simple search for factory in the graphics section should work. As for the foreground, it's so not detailed that I believe if there were more details to it you wouldn't have to spam all the ground tiles in the first place. I just looks rather dull and flat in it's current state.
For your palette, it consists of just too much orange, too much brown, too much yellow, and so on. It's all just too much and looks overbearing and monotonous. I'm sure you could add other colors in there with ease, like add multicoloured pipes to break it up a little.
