During my tests with geometry dumps from OoT some time ago it was nearly impossible to find any areas that used even 3000 triangles including characters, effects, and such. I believe the highest the N64 was supposed to handle was around 3300.
Your images look like pretty good recreations, kudos for that, but apparently you've got more polygons. Looking at them, it seems you either have a lot that are overlapping, or several faces with way more edges than any should have. Either way it's pretty messy from a technical stand-point.
