I have an audition at the army school of music at the end of the month.... I need to know what people think of study no 76 from 80 graded studies for clarient by Muller (on grade8 abrsm) and no 5 from visions by Paul Harris

Theyve said that they want two contrasting pieces, and they are, but theyre very short I was wondering what people thought and are there any other suggestions... cheers in advance
