It's really rewarding to compare the images and try to figure out what's changed. Eyebrows are a good example I think, and the length of Joe's arm in the last panel.. 
I actually spend way too much time switching back and forth between the original and the updated images on the computer whenever Jessica updates things like this.
The speech balloons are definitely an improvement, makes it seem far less cluttered when there are multiple connected ones on a page.
Agreed. After we finished Issue 1 and had a few copies printed, we compared the size of our text to several other comics and found that we could reduce the size of ours a little bit. So we did that with Issue 2, and now Jessica finally went back and updated the text in Issue 1 to match. Having smaller text gave her more room to play with balloon placement.
