I came here on a whim, and behold! you had updated.
As usual the art is above-par. I love Shredder and Krang, so I was enjoying their interaction, especially since their partnership is deteriorating. Funny how Shredder announced the high-tension double-betrayal would have to wait once the turtles arrived.
However, I really think you need to improve your grammar--when to put apostrophes, commas, and the like. For instance, "you are" is "you're" not "your." When a character adresses another chracater, use a comma. For example:
If the name is the start of a sentence:
Shredder: Krang, shut up!
The middle:
Shredder: Shut up, Krang, now!
The end:
Shredder: Shut up, Krang!
Anyway, your comic is great, and I look forward to more, especially since the story hasn't technically "started" yet.
