If that is the look you want, then it's fine.
If you want softer, more rounded and more "pastel", you would need to change the diffusion and distance and direction of your light sources.
The Metz 45 heads are fine, but they lack a modelling light, so it is a bit harder to experiment before actually shooting.
If you have the chance, shoot a trial roll or two with a number of lighting experiments on it.
If you don't have the opportunity to shoot a colour trial, you could learn a fair bit about the right lighting with B & W.
