Thats actually really good. Though i wish you could do a few things more with it.

Mainly, make it a bit longer by adding in some slow, floating objects like asteroids, or cubes. As well as making the words come in slower, and slightly delayed. Maybe even add in the text: Space is the Place instead of Cartoon Cartoon , which dissolves, then add in the Toonami aftermath Logo in the same manner as the original, only bigger.

The bump probably only needs to be about 15 - 20 seconds in length, and 20 seconds is the longest i would make it.
 

Seriously, this is really good, you only need to make it longer.

*Edit* I am not a mod/admin/staff or anything, these are just my personal opinions. If your interested, i have made music for people to use in bumpers and promo's. Here is a link to the Thread: http://www.toonamiaftermath.com/content/anybody-here-writeproduce-music-or-songs

Not bad. Although making it a bit longer wouldnt hurt it tbh, or you could also re-work it to make it the Cartoon Cartoon intro somehow and have that intro end with that, but that's just an idea I'm throwing out there. Also this is just a nitpick but i just feel like its too dark to be associated with Cartoon Cartoon, needs to be more lively and colorful I think.

other then that, this looks fantastic.

HAHA, awesome that you used my Music!

and i am almost afraid to ask you to tweak it a LITTLE more to make it smoother in terms of the animation. But i am unsure of what program you're using.

Let the music play on for a little bit longer. and then make the video go black in the Adult Swim Style using:     Say Gold.

With the period after Gold.

I am making this post quick, and i don't want to keep frustrating you with more tweaks and critiques. but alas, I am an Artist, and artists are cursed with an unending quest for perfection. (Its not as bad as it sounds).

Work on the ending a bit more, and try to make the first transition a little bit... cleaner? or Smooth.
