The Syllable Structure

I've been working on my conlang for several months now. Since it is my first one, I go on about it with careful research on every single aspect of the language. Last week, while reading "The Art of Language Invention" by David J. Peterson, I realised I hadn't worked on the way the syllables were structured. The book explained it like this:

A syllable is a prosodic unit of measurement used to divide words into smaller parts. A syllable itself can be divided into two main parts: an onset and a rhyme. (...) The rhyme can also be subdivided into two parts: the nucleus and the coda.

Taking this into consideration, I searched through my dictionary to see how I had structured syllables naturally. I saw words like Väma (CV.CV), Krulo (CCV.CV) and Lottur (CV.CVC). So it seemed evident that the nucleus would always be formed by a vowel, and I had yet to figure out how the onset and the coda would work. I looked at words like Maeda, where in the first syllable (‘Mae’) there were two vowels. So I decided that the nucleus, a vowel, could be either a monophthong or a diphthong, still represented by a ‘V’. (Take into consideration that there are sequences like ‘ai’ or ‘ue’ that are not considered diphthongs).

When I got into the consonants, I realised that I first had to establish which consonant clusters my conlang had been allowing naturally and which not, as though to create a cleaner set of words. Sequences like ‘tr’, ‘rd’ or ‘kr’ were allowed either in the onset or the coda, and a sequence like ‘st’ was allowed but not on the onset, or like ‘rt’ but not on the coda. For example, look at the words: Aarkida, Litro and Dratto. 

So, I understood that a possible syllable structure would be (C)(C)V(C). Where the ‘C’s (consonants) were optional, and the vowel was mandatory. But then I questioned, could there be larger structures like (C)(C)V(C)(C)?

And after reviewing words like Phrenkta (CCVCC.CV) (treats the ‘ph’ as one phoneme), or Kruntsa (CCVCC.CV), I arrived to the conclusion that (C)(C)V(C)(C) would be an appropriate syllable structure for Phošug’s phonotactics.
