The title of this animation is "Give me criticism pls"
-There's no environment.
-It's too short.
-The agent hesitated. He was already pointing at our guy, and he's dead because he didn't shoot.
-The very first frame is shown with our guy at the ready, and the agent leaned back, in a full shot, with two sets of identical floating hands above them. It seems like an unintentionally visible staging area.
-There's no sound
-There's no music
-There's no signature or credits to prove that you made this and you, smooth-Pb, didn't just lift this test from somebody else. And because it strictly adheres to the on-model style and presentation of Madness, something made by Krinkles, there's no real personal ownership to anything that's happening here.
Were these assembled using assets that were created by somebody else years ago, or did you draw custom graphics for this animation? We'll never know, because that's an inherent limiting factor by doing fanmade Madness animations.
Though there is something endearing about seeing the same kind of styled animations, more than a decade after it debuted- one has to consider how long is that going to last?
It excels as a testing platform, because you have the opportunity to cut your teeth as an animator, but I hope that you're taking the time to also practice on your artistry, enabling you the acuity to generate custom environments, props, and character designs as you see fit for whatever it is you're making in the future.
The only way to do that is to put in the time. An animator can only get to a certain point by repositioning and tweening assets here and there. At some point, you're gonna have to start dabbling in other tools. I encourage you to challenge yourself by stepping outside of your comfort zone, and really swinging for the fences in your future tests.
