DataBaseGeneric namespace: {Company}.{Product}.{Module}.Entities DataBaseSpecific namespace: {Company}.{Product}.{Module}.SqlSpecific

BLL namespace : {Company}.{Product}.{Module} references DataBaseGeneric & DataBaseSpecific assemblies

PL namespace : depends on the presentation media references only BLL and DataBaseGeneric assemblies

Nothing wrong with that setup.

And as for the Namespaces, use any convention that suits you.
