Alien: MONDAY Okay, two things: This is great. The effort is obvious, the voice acting is good, the artists are clearly good, the shot composition is good.
And now for the issues, which I find more interesting: There's too much focus on having INDIVIDUALLY pretty frames. I understand why that's desirable, but the focus on having a lot of frames makes every motion take too long and takes away any sense of speed in a motion, and every frame being at the level of effort a traditional anime would reserve for "Good" scenes means there's no sense of focus on important scenes, which would traditionally be highlighted by higher quality art. Secondarily but maybe more important, the focus on indiividually important frame means there's no smear frames, which also contributes to motion feeling slow and morose when it shouldn't, really no contrast in how fast any given motion feels. Imagine if most of the movie had a more traditional approach to frames and, in the scene when the chick is thumbing through the cameras and the alien crawls in, THAT scene suddenly had the milky smooth animation. It'd sell the threat much better.
One of the biggest strengths of traditional anime imho is how damn good it is at frame economy- think dragon ball fights "Cheating" and having multiple movements per frame, or sailor moon doing a whole scene with like five frames of animation because it pulled back on frames to make a slice of life scene be more cartoonish. If you can drop the (Understandable) idea that "More frames is more good", and study and apply that you'll see very immediate returns on the quality of your animation.
