Yes, the issues in my oppinion were the hand (actually the whole arm is in bad position), the table, the colar of the blouse in the back and the neck forming a straight line with the chin and cheek. It's also twisted, showing perhaps too many wrinkles.
As for the arm and the table Mike, the wizard of digiphotos, have found a great solution
But if your mother is close, I would consider arranging another pose, thinking in advance. Make some sketches first and after you decide which one is better you try and put her in that specific position.
