Well done, mate! 👏

I would say the following are some limitations of poisson regression:

Nonlinearity: since it's a linear model, the model will not be able to apply to nonlinear relations or data.

Sensitivity: the model is so sensitive to the outliers that if the data set is overdispersed, poisson regression is not the perfect choice.

Difficulty of interpretation.

Rightly said, Mohammed :)

Adding one more to this, as we are assuming data comes from a Poisson distribution, it is assumed to have roughly same mean and std-dev.
