I agree with Wayneb's post above. I realize this is probably not what you want to hear. Learning from critique ain't pleasant, but it can work. Don't get discouraged, but really you're trying to add details when you need to nail the anatomy and establish in your head a very clear idea of what you want the figure to look like when completed. If you have a clear idea of the final figure now, can you provide us a drawing or photo?
The 'kilt and legs' photo below looks too broad in the butt and waist.
Your 'armature' posted earlier was a good start. Suggest you return to that point for a bit. The waist needs to be narrowed, the hips narrowed and the shoulders rounded. Add pectoral muscles to the chest and shoulder muscles. You don't need a lot of detail on the armature and no extraneous depth or thickness. Remember to keep it skinny. When you think you've got it, smooth the surfaces with steel wool, so the clothing and equipment will go on and fit properly.
If you are using kit parts for any part of the final figure, hold them in the proper positions on the armature if you can just to get an idea of how they will OR won't fit.
Before you go any further, put the entire armature in the position you want the figure to be in and secure all the joints and the waist. Personally I put the head and boots on the armature at this point, but others do not. I never add the arms until all other parts of the body, clothing and equipment have been put on.
Since your Scot will be wearing equipment, you have to allow space and depth to make it look right. Skinny armatures are part of the answer to getting this right. Another part is having enough reference photos to know how much space all the equipment takes up once the figure is 'wearing' it. I've provided a few reference photos. Remember that if you are doing an action pose, you need to adjust the equipment to the correct positions - not now - just something to remember when you go to that step.
I can't tell how you secured the armature to the base, but make sure the armature is on good and tight. Most use wire running through the skeleton of the armature, through the foot (boot) and out the bottom of one or both boots into the base. You'll inevitably be pushing on the armature as you sculpt and cut and if it isn't secure, a black cloud will appear over your head and (again, just speaking for myself) you'll say some of those words.
I recommend that you concentrate on the armature and re-post photos of it from several angles.
Hope this helps!
All the best,
Dan
