I remember making something like this that I posted on Knux's Forum 3 years ago... It was just the normal SMB3 Pipe middle with curved black outlines...*chuckles*
Well, this looks very good. Airship, your graphics are amazing and continue to inspire. Keep up the good work.
I like the updated pipe a lot, it reflects SML much more now than the old version. It looks like it might have more potential than just for being a pipe. Great work.
