After Blocking I now know what the pages will roughly look like so I can now safely start penciling. Since I am my own inker I can be a little loose with my pencils, but not too much. At this point its very important to keep in mind that I still have to add word balloons so I need to keep some areas open for those. The trickiest part here is making sure that characters in similarly laid out panels look very similar to each other, in placement in the panel and in how they look. New characters I'm not very used to can be an issue and I need to be careful with them.
