The cloth is very much worth of learning - there is one strong reason for that: observation. The best way is just to simulate something similar to what you want to achieve sculpting. With simulation you have the advantage of observing why specific areas of garment are folding in away adeqaute to given parameters thus you can learn to understand and sculpt the cloth with a precise aim and not just copying what you think is visible for you on a photo. This is a huge difference on approach and the results are so much more believable. It's the same way you learn the inside anatomy of a human to model the outside hollow skin shell - when you know how things work you don't have to guess.

Awesome sculpt. Could you give some insight into the workflow you used to create the bow and sash around his neck. Great work.
