Hello again. I know that this time of year is not the best for some of the others to come in and critique cleans. I can't handle the challenge four image though so I won't be critiqueing that one. Otherwise I will do my best to stay on top of things here as I do my other work.
A good job I see you took what I said last time and applied it. The blacks as much improved. The page is straightened nicely. Your borders are much better with a couple of minor exceptions. The grays are looking pretty good too. Now I need to talk about your lines. When you are making any lines that are not perfectly straight lines you should also use anti-alias. If you were using stroke on the text bubbles and used the pencil tool to stroke the black lines don't. Use the brush tool to stroke text bubbles and any lines that are not perfectly straight.
All panels: Text bubbles are two jagged from lack of anti-alias.
Panel 4: The border on the right has been overlaped with the text bubble layer and now looks bad you need to fill in the border so that is the same size as the rest of the borders. The speedlines you redraw do help bring out that faded area but I think maybe they didn't have anti-alias on them either? The look a little jagged. Since you don't want the redrawing you did to stand out more then the actual drawing on the page I would have reduced the opacity of the tool you were using to make the line to around 80 percent (in this case) to more closely match the other lines.
Panel 7: The redraw is nice enough except for the lack of anti-alias. Again your lines are to harsh and jagged without it and that makes what you did stand out and look like you did it. Your goal should be to make the redrawing you do look like it was always there not something added in later.
In general you did a good job. We just need to fix the anti-alias thing. Hint for straight border lines I don't use anti-alias because I want that sharp and clean edge there.
I hope this helps.
