At the beginning, I was thinking of incorporated of characters interacting (waving) with each other . However, it would make the logo to be packed. After taking a few looks on the character, I realized that their hand could be fused into the letter N. The sketch of the characters and N is added down below.
Sketching the frame.
Adding the outline.
Thickening the outline.
To maintain the overall square shape (as requested) the "TH" was added inside the N.
Variations to the logo. Added "society" at the lower part of N.
