Using the formal analogy between the Dick superstring inspired model and the problem of the building of an Eguchi-Hanson metric in 4D N = 2 harmonic superspace (HS), we derive a general formula for the quark-quark interaction potential V(r) including the Dick confining potential. The interquark potential V(r) depends on the dilaton-gluon coupling and may be related to the parameterization of confinement by the quark and gluon vacuum condensates. It is also shown how the axion field may be incorporated in agreement with 10D type IIB superstring requirements. Others features are also discussed.
