I like GPS Squad its really interesting, no matter how random it gets. I watched GPS ep's 1-3 so many times I cant fathom. Unfortunately ep4 wasnt that great at all.
The fact is that GPS is no longer in 2d, so your now under a entirely new set of "rules" to get the same effect. Major Laser is honestly the only person I can say that kept his "cool" from Gps3 to 4, attributed to fact that that is his character. 2:55 to 3:14 & 3:31 to 3:38 where the best seconds of the episode along with the shots @ 6:41 & @ 6:42 the rest of the episode felt flat due to the Framing and Especially Lack of Exaggeration. I'm not sure if you're familiar with the 12 rules of animation, but GPS3 used more of them.
I know first hand for how insane a 1 person project already is; It's challenging enough. Sadly I must say GPS4 looses the edge GPS series has had up until this point. If your gonna keep it in 3d they're are a few things that need to be done to bring back the edge it had b4 4 ...lol
1. MOST IMPORTANT PUSH YOUR ANIMATION, using squash and stretch, arching, & follow through techniques (12 rules of animation). I know your models can break if you push them too far but look at Toy Story, look at a the way Buzz moves, He doesn't physically deform but his gestures have weight to them, and his poses have "stretch" to them. Yes this based off Japanese animation but remember that was originally derived Disney animation. A lot of your animation killed your jokes in this ep, and made the delivery stale, your animation can make or break your work, which is why some people have said to revert back to 2d.
2. Frame your shots better. It was very weird to see 3:15 the guy is is plain sight in the center of the shot in a barren room with nothing to hide him in the slightest, what makes it more awkward is the fact that that person is not even in a corner or somewhere like he's TRYING to hide something; putting his crouching out of context...... and making him just THERE with a small arrow to point him out even further. Nothing about that shot "worked" It took away a lot more than it added.
3. Lighting, Effects, and Consistency. Even a random show like this has consistency, you need bring back all the Backgrounds and the "abusive" way you used them in GPS1 2 & 3. You also need to Light your characters to fit the mood. For example A Horror under-light or well placed effect Background would have been perfect for "you completely worthless heathens..." As well as when that dude shows up with the camera. that would have been a perfect moment for snapshot effect/flash . As for consistency, keep everything in 3d unless you need a 2d element, it was so odd to see the school as a 2d image and the hall way as a 2d image when they should have been in 3d. For that hallway shot @ 2:55 you could have rendered out a nice HD image then use the fish eye warp in Photoshop to get the same effect or Shoot it at dramatic angle, especially since every other location is in 3d.
4. Have Chibi models of needed characters so you can switch out at will. Check out the intro to Vocaloid Project Diva 2 those would fit quite nicely.
Well this is all a learning process anyway. I love that this continuing, and it cheers me up its just good. I love the energy, the vibrancy. And if you need any thing like a look over or some more suggestions or something I'm pretty much here to help just shoot a pm er what ever. Just Keep pushing for the stars. Fly away (lol) :)
