Hello everyone!
I am going to join a piano competition in the end of July and I'm choosing one piece for the competition.
There're two pieces for selection.
1)Mendelssohn: Songs Without Words Op.102 no.4 in G Minor
2)Schubert: Impromptu Op. 90 No. 2
May someone point out the most difficult part/techniques of this two pieces?
And what do you think the difficulty of this two pieces if rank them out of 10.
I want to know more about the style of Schubert, is this Impromptu a typical works from him?
I am struggling with these two, any suggestion, advice, warning will be appreciated.  Thank you very much!

The Harmonious Blacksmith is easiest to handle.

Which do you like better? Pick that one. You'll practice it more and you'll play it better.
The Schubert, in my useless to you opinion, is easier technically and musically
