What are the real differences with the Jo Twins? >~< pls help! I still can't tell them apart!!!

-Youngmin's jawline is softer and madami feminine while Kwangmin has a longer jawline
-Kwangmin has a slightly deeper voice than Youngmin's
-Youngmin's bang is on the right side (his left side) while Kwangmin's bang is on the opposite
-Kwangmin often put his bang to the upside.
