How to NOT make my Constructed Language look like a cipher?

I am making a language, I got many words, but I am frustrated when it comes to deciding on a grammar structure; it's too much like english still.

I am teaching myself (using wikipedia) various grammatical structure, and learning the difference of word orders like typical Subject-Verb-Object and Subject-Object-Verb.

Now, I wanted to the keep the Word Order SVO, but I have trouble telling the difference between grammatical structures of other languages... I don't want my language to be a cipher of English.

Are these grammatical changes sufficient?:

* Modal verbs( e.g. Must, will, do, want, etc.) occur after object, example: zĕ tarad hæm ashrųd nĕd, which would be "I lead him-will not"

* adverbs occur after the verb: zĕ merkh ųven zar 'kanų'. which would be tranliterated as "I made-easily this 'canoe'.

* compound words are reverse compared to english and are grouped into two:

--Words that are joined by "dĕ" (meaning "of"), like "bottle of water" instead of "water bottle"; 'roket dĕ fazia'

-- words that are joined by "ẃ" (pronounced "za") which indicates a compound relationship between the nouns, example, bædii ẃ ýkin, tranliterated as "books-text" or textbooks in english.

Sufficient?
