@Kevin-Longueil It's never too late to learn new tools and software! That's a stigma that's gotta go. I feel like I'm a mirror of your journey. I've been learning to sculpt in Zbrush over the past 6 years and now getting back into illustrations.
I've only used Nomad once but I'm guessing it can export obj or fbx extensions, which you could the use in any 3D package, like Zbrush or Blender for texturing. In Zbrush you'd probably use projection master, spotlight or paint by hand.
@MissMushy Well done for your first go through! Keep it up. Keep posting. Once you get familiar with the tools it becomes so much easier to focus on the creative!
For both of you another option for sculpting is Blender. It's a bit more robust so it can be intimidating at first. It is a one stop shop for 3D (sculpting, texturing, vfx, rendering, animating, etc.) but they have a bunch of tutorials, support and have been gaining a lot more traction as a lot of pro artists and some movie houses are gravitating to it. It is software that I've been wanting to add to my belt for awhile but priorities have been keeping it on the back burner. If you do want to try it this is the best Blender crash course tutorial to get you up to speed. Highly recommended.
