If you would want to lose the noise, try NeatImage. It's a really great program that removes digital noise.
I like the message of the picture. The picture itself could be better if you where photographing it from a further distance, so there's more wall visible. I guess that is in your home, so it is hard of course, since there are more things in a room than just a wall and stove. I like photos where there is a big empty wall and then something that makes a great contrast, like a stove. ;)
