I have not money to find a teacher. But I want to gamble the ATCL. Would someone give me some advice that how to choose the piece?

Recently I'm practising Mozart Sonata in C minor, K. 457. I love this and want to use this.
What other pieces should I choose?

I like minor piece.
I like listening to Bach but I guess Scarlatti is easier for me. Now I'm practising Bach's Fugue 847 (not in syllabus) and Scarlatti 259&260.
I play contemporary music on electronic bass. So I want to choose some 20th-century stuff. Is Boogie Woogie Llanoogie a good choice?
And how about Chopin's Nocturne?

May look silly but I just want to gamble once. Thank you everyone.
