I think you're looking at tuts the wrong way, it's not really 'monkey see, monkey do', they're more of a learning experience, whether you follow each step to the point of creating the same outcome is up to you, just read them so you learn new techniques and styles that may fit the best with you.
As for your sigeh, good job with the text, for 15 min I think you did a pretty good job with it, but your focal is immensely suffering because it doesn't blend with the background to well. Your whole sig looks purple yet your render has completely different lighting to it.
