My First Definition: Snakes?

Followed a Tutorial and created an interesting bulbous shape.

From there I took what I learned and made my own design. Based on how I thought the tutorial shape kind of looked like a snake I decided to run with that idea with my own design.

Through making this design I had slight difficulty replicating the designs, but I think I was able to figure it out mostly, unsure as to why the loft boxes in the replications is orange?

I wanted to change the colour of the loft, however after some trial and error I was not able to figure that out, Some green and yellow snakes would've been cool.
