please give your honest opinion on this background... I'm really not sure.

Maybe some mountains un the background? The green its a little confusing to me Pretty nice work BTW

It looks really good!

To be honest I'm fine with it!

The pipes are a little too dark. That's my opinion.

I love it !! Looks realy good keep it up! Boy I can't wait to get this program! :)

I like it, the background contrasts with the sprite so we could see it better

So the repeating buildings don't annoy anyone?

There's a break in the center where the background tiles don't match up.

I might if I played hours of it but not realy. You should always add a bit of variety though .

I like it. It's nice and simple, but would be more impressive with more parallax :)

It is parallax!

how many layers? separate them by 3d!

How can i make a background?

2 layers atm, the background is being drawn with GCOPY from the sprite page.

interesting. Yeah, I like the art style, but I do think that having the background elements on different parallax layers with some 3D separation would add a bit of visual pzazz. It's more important to have a working game before any of that though. Keep up the good work though, and don't worry, it looks very nice as it is :)
