The second and Fourth photos in this progression provide for the best viewing angle on the trunk. When doing Mugos you always start with the trunk and nebari if possible and work up remembering the base of the trunk is the most difficult problem to solve and the most obvious attention attracting feature of any bonsai. If you build your bonsai with this in mind you will have a decent bonsai. So for now you know, at least from what I can see from two dimensional photos, the two best fronts of he tree and the reasons for that. Now we need to determine what's next?
Let me know what you think when you have some idea. Small or large, don't pre-judge or think I would like this style or that style, look for what the tree is doing and see if it says anything to you.
