Yep, that is generally fine, with the possible exception of the poles on the cap and the base where you have allowed the horrible triangles / complex poles. Oh, and the normals are wrong on the base and mid sections so you'll wanna reverse those.
Nicer solutions to the end sections would be either...
...which makes the pole much less complex and eliminates the Tris, or this one...
which is nicer still, being all the quads and NONE of the complex poles ! And, if you do change these don't forget to do the same to the insides too...
