3 months is too early to think about a revision unless something has ended up drastically out of place (often due to trauma). The final shape will not been seen for at least 6 months to 1 year or sometimes longer. In particular, the relationship of one part of the nose to another will change as the nose heals. The tip may rotate slightly leaving what looks like an excessive dorsum now just right when things are fully healed.
It is difficult but patience is the working rule here.
