The first part was flowed quite well at setting scene, not 100% perfect as it just feels so rushed.. I would have made the Liu and Raiden training bit run on for the full page. Having that last scene with the others there throws me off, you should at least made that last cell have another bit with Raiden and Liu in and then have the others on the next page. It doesn't really fit in with what you got thats all.
If I hadn't have seen 1000+ Fanfics that start off with sending someone off on a quest I'd properly have said the intro was intereasting. ^-^'
^o^ 4.5/10.
Still not good enough though for a good rating, but better then previous comics. Needs backgrounds still. You really should learn how to get them in. They'd greatly improve this.
edit:
One more thing... Straight lines please. wonky lines for each cells look scruffy. From memory you only have to hold down shift key and it goes straight automatically. At least in other programs that does the trick. :?
