Trouble drawing lines with CMC and powder frit

I have been looking at this site for some time and really appreciate all the info and help this community gives.
My Fusing Problem:
I have attempted to use the CMC + glass powder (Richard Lalonde method) to draw on glass and have run into a problem with the outcome. Please look at the two pictures below. You can see that the black lines seem to have pulled away from the center of the line.
What I did:
a) 2 pieces of 96 COE clear glass
b) Mixed up some CMC and added glass powder (for the square image I added an extra layer where I thought it was too thin. For the round image i added more powder to the mix. Each one was dried with a hair-drier before firing)
c) Used a “Bubble Squeeze” firing
What I think is going on:
In the square image, the dark part by the “3” got a couple of thin layers and came out dark black which is good. (I thought if I added more powder and made it a thicker concentration, it would work) NOT SO!!
Could the bubble squeeze firing be too intense (8 segments) meaning too long at 1465 F (20-30 min). and got movement in all directions and thus got this separation. It looks worse in person than the images. (The part in the black lines that appear white-ish is actually clear)
Looking forward to your insight here.
Sorry, Had trouble posting images from photobucket (take a look in the community gallery!!)

Take a look in the community gallery for the round and square images I talk about in my first post.
