Calling it a "fear" is probably an exaggeration but it looks good as a title so hey.
While I've been using MD for some time now, I always feel uneasy when I go to unknown territories as it seems easy for everything to fall apart on the program.
Having started working in elite3d, I met so many talented people that are comfortable in doing lot of things -one of these being Marvelous Designer. Therefore I feel it's my duty to get it together and get more familiar with different things in MD. Therefore, backpacks!
Here's a backpack I made last weekend, no Zbrush, pure MD. The goal was to see how far i can push the work without going to Zbrush. Of course in an actual pipeline, you'd hope into Zbrush, put stitches, zippers, memory folds, clean everything up and prepare it for retopo and texturing.
Next onto maybe some more backpacks, or some complex clothing work, cheers!
