How to improve mesh quality for wing analysis

  Hello everyone.
  
  I am doing external flow analysis on a airplane wing. Even though the results are coherent and realistic, I am struggling on improving the overall mesh quality. For example, the average orthogonal quality is around 0,77.
  On the mesh, I utilized the capture curvature feature, inflation layers, edge and facing sizing and a body of influence. I also tried to insert a face meshing but it went wrong. So, there are some features and tips on generating the mesh that i am missing? Which techniques could I use to improve the mesh quality?
  
  In advance, thank you very much.
  Here are some images of the mesh:

  For tets I'd focus on Skew and not Ortho Quality. Both are valid, but I'd tend to leave Ortho for poly cells.
  Re the mesh (as opposed to cell) quality. Reduce the growth rate(s) and also review any surface mesh sizes. Check the inflation settings as the jump from inflation to first tet is a little large.
