There are some exceptions, sure.

But German pronunciation is 80% simple and regular at least whereas English is more like 80% complicated and irregular.

Compound words do have the potential to throw this for a loop. The pronunciation is regular if you can decompose the word, but if you miss where the word boundaries are all bets are off. For example "linkshändig"

That could be true for some words, but not in your example. "sh" does not exist in any basic German word, so the boundary must be there.
