I'm making a set of steampunk-ish type pipes, Heres what I got so far.

I'm going to have a background and all the sets I make are going to be able to link up besides the first and last, I would also like to note, I'm missing the cap at the very start to close it off.
Edit: Also I am in no way good a pixel art, I just needed something to do. I'm also going to make it look old and worn.
Here is the worn.
