In this sentence the writer eagerly waits for the final outcome ( perhaps how his artwork is acclaimed), and that response from others has the final say on the creator's mood, dejected or elated. The work would perhaps bring him name, fame and fortune. As to its construction, it is nonetheless syntactic, but poorly worded.
What turns out of something, is the end result. It would be better if we leave " turns out". But if we consider this from another perspective, "turns out" may be justified in the sentence in the sense the outcome may be for the good or worse. But we're squeamish about the clause, "what I truly feel" where the intended sense is something else : " what it means for me". You see, my feeling about my creation is essentially subjective and anything exterior to me can ever change that.
So "turns out" is not redundant better let's try to express effectively in the 'what-clause' that follws it.
