I am still new to art in general and I only draw once in a while.
I don't know if there is something I am missing or if I have just not yet the skills it takes but I tend to get stuck between the sketch and the linework. When I finish the general idea of what I want to sketch I look at it and always feel like I need something more before I can go to doing linework. Especially since I'm bad at linework. On top of that, I still do not understand how clothing works in drawing and if I need more lines for folds and stuff before I can go to the finishing steps.
The particular piece I'm stuck on currently is this:

Once again I am stuck so I thought I come here and just ask some people with more skills and knowledge. What is the best thing to do when stuck between the sketch and the linework? Is there are a method to get a better understanding of the general picture before starting the finalizing? Am I missing something or is it just practice, practice, practice that can help to get unstuck?
