You did well here.
Each language allows some consonnat clusters while others are not allowed. Neither English nor Polish are exceptions in this regard.
For instance in: ńł
(above) the ńł
is not possible in Polish.
Additionally, some consonant/vowels combinations (such as "ćę") do not occur in Polish.
Bottom line, the challenge of the original post is not an exercise in the Polish pronounciation.
