I did it again ... but this time not as pretty as the previous attempt.
I know where I went wrong, I didn't let the rolled out dough relax before I rolled it up, therefore, after I rolled it up, and the dough strip relaxed, it actually squeezed the inner rings upwards, creating leaning towers of mantous... After being steamed they were even more protruding and some pieces looked obscene, as commented by Mike.
Actually this is the usual time, but I don't know why for this post, it took me 4 days.. sigh!!
And I shaped some dough to be like these.....
The final result!!!
The colour's more toned down after steaming.
