So, in photoshop, what I do is goto brush settings (that icon right under the word "image" up top, if you have trouble finding it). You then go into Shape Dynamics and set the Size Jitter [control] to Pen Pressure. I also turn on Smoothing. Of course, some brushes will give a better look in regards to what you're looking for, however, I pretty much use the default round brush for everything (sometimes switching between hard and soft). Lastly, you can take a look into using other programs that already have pencil-like preset brushes, and/or just give a better sketchy look than photoshop, such as: Paint Tool Sai (debatable, but I rather sketch in this program and paint in photoshop) Autodesk Sketchbook [whatever edition] Those are the only two other program, I've ever used, though there is still Manga Studio, etc.
