Severe crowding with impacted canine

A 15 year old patient was presented with severe crowding with buccally impacted left maxillary canine. Extraction of the upper and lower first premolars was done followed by surgical exposure of the impacted canine and fixation of brackets. Alignment and leveling was done for the upper and lower teeth as well as guiding the impacted canine to occlusion. Any suggestion or opinion is welcome for future improvements.
