I have a working 2x2 elevator I just cant get the down circuit timed right

Anyone who helps will be the first to see my design. Its very compact not like these giant ones people have been trying to make and its base is 4 pistons very
roomy

and it can be taken from bedrock to sky ceiling if u wanted to

Can't wait to see the final product you create. Hope you get help you need to work it. (I am Rubbish with redstone)
