Just off the top of my head, page 6 may have a new panel (Clark's foot?) and the x-ray vision effect through the mask (and now the hat) seems re-done...
One thing that strikes me is that the many small ink marks that make up the professor's face in his first appearance are fairly different than the broader ink lines of the last two pages.
1. Nope. As I said subtle. New hint: it's not necessarily the inking.
2. As above - what you see here is a difference between Bob and Shane - both wonderful, IMO, but just a difference in their styles.
I hate to say this, and its just me, but I actually think the new "splash page" with Superman fending off the boulders has too many extra inked rendering lines...it looks a little different overall, and I think it makes Lois look less attractive than the original.
Just my opinion, though...
Ouch... (it's ok Angel. You started this development on this thread, so you can deal with it.)
Funny though, I thought she looked more attractive (although I thought Bob's was cool too). I just couldn't resist doing this page for myself. But I can see how you'd feel that way.
Oh, the heck with it...
Page 3 - Lois used to be taller than Clark in panel 4 when they were sitting in the car. I don't know what I was tripping on that day - but after it was inked, it really stood out.
Page 4 - look at panel 1 and 6
Page 6 - panels 3-5 and 8.
What was driving me crazy was a significant lack of texture and background which I didn't get in there. The inking on the original pages in most cases were so full of character in the backgrounds, that after coloring - the barren backs stood out like a sore thumb. So, I digitally drew in the inking and backgrounds using a nifty program that is called "Manga Studio". (I love this program.)
Anyway, I'd better bail before I inadvertently experience any more humbling critiques...
