  We show the role played by QCD evolution and skewedness effects in the DVCS
cross section at large $Q^2$ within the color dipole description of the process
at photon level. The dipole cross section is given by the saturation model,
which can be improved by DGLAP evolution at high photon virtualities. We
investigate both possibilities as well as the off-forward effect through a
simple phenomenological parametrisation. The results are compared to the recent
ZEUS DVCS data.
