Sebastien looks awesome, great job on the tattoos/scars. I really have to invest in one of those guys at some point (ideally when my desk is cleared off...)
Quick question, as I recall the base model for Sebastien has pointed ears, it's unclear from the photos but did you trim them? Just curious.
Also, the full sculpt looks like a good first effort but I'd definitely suggest having another go at it. The main problem right now is that he appears to be wearing a full-body puffy coat. You've got most of the dimensions spot on or at least close enough but beneath his hood the character looks rather statuesque while the rest of him as an unnatural paunch.
The good news is that you can do this with minimal new sculpting required, all you need to do is trim down what's there though i'd suggest removing the hood and reworking it from scratch. Since it looks like you're using an actual 54mm presculpted head you can mix some green stuff, flatten it out and then take one of two routes: either apply it immediately which will give you a little more work time but make a natural cloth feel a little harder to achieve or let the putty cure for about 45 minutes and then cut it into shape and apply. The problem with option 2 is that the shape of a hood is very difficult to precut and you're likely to end up some extra GS "cloth" which needs to be covered up retroactively once it fully cures, which isn't too difficult.
As for the rest of the model, I'd say just go to town with a sharp hobby knife and some files. If you take off a little more than you intended then just sculpt it back on. You can easily find samples of what to go for by searching images of robed people on google.
Anyway, hope that was helpful!
