Also the 2nd stage is not a differential amplifier. It acts as a common mode amplifier. Additionally, since you have alternating NMOS and PMOS input stages, check if the output common mode of 1st Op-amp is enough to keep the 2nd stage input MOSFET in saturation. This may not be relevant to your question.
