Pay attention to the articulation markings which define the elegant character of the piece.
Comparable difficulty and character — good candidates for what to learn next.

You should be comfortable at Henle level 4 — meaning you can already play level 3–4 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
A typical performance of Albumblatt lasts about 3 minutes.
