It's true, I almost mentioned multi-word expressions because I recall that it was a sticking point when learning the language. That being said German loves compound words and those can get a while to get used to as well. Phrase structure is also pretty different in German, with a propensity to put the verb at the end of sentences in some forms. Adjective order however is not really a problem IMO, it's irrelevant while consuming the language (unless a text tries to convey some meaning by purposefully miss-ordering the adjectives) and in general getting it wrong while producing English will make you sound foreign but shouldn't hurt comprehension too much. Saying "the red big house" instead of "the big red house" will raise some eyebrows but should remain understandable.
