Same problem here, I also ordered the Clone Wars cartoon images. Some were top notch, others were horrible.
Here's my review from RS:
Since I bought all 12 Clone Wars cartoon photos, Ill go through each and describe any problems:
Yoda: Would have been my favorite, but is the most obviously pixelated. All lines are jagged, and look very "computery".
Anakin and Clones: Pretty good quality, slight pixelation in spots, you need to be looking for it
Asajj Ventress: About as bad as Yoda
Battle Droids: Cant see pixelation from a normal distance, on par with Anakin and Clones
Clone Troopers: Not as bad as Yoda or Asajj, but a bit worse that Battle Droids and Anakin and Clones
Dooku: About the same as Clone Troopers. Middle of the road, not very noticeable.
Defense Team: Very good, pixelation hardly noticeable, only visible in certain spots
Durge: About as bad as Yoda and Asajj
Jedi Heroes: Good quality, on par with Defense Team
Jedi Heroines: Probably the best one of the bunch, pixelation only noticeable in very minute areas.
Palpatine: About the same as Dooku
Republic Forces: Also very good, almost as good as Jedi Heroines, better quality than Jedi Heroes or Defense Team
It seems like only the characters are pixelated, the backgrounds (if there are any) are clean and crisp.
Im more upset about the creased corners than anything; they should take better care in shipping their stuff
I'd love to use these as autograph fodder though. I have Genndy Tartakovsky's and Paul Ruddish's autos, but I want more artists and the voice talents
