Thank you for taking your time on evaluating all of the GIFs and putting your input. For the ratio difference you raised; every Tom and Jerry GIFs were made with an aspect ratio of 640x480 while the rest was made by 800x600. But all GIFs are made according to the requirement (1:1 - 4:3 / 1 to 1.33333... ratio).
Even though I agree with few things you've said, like #39 that Tom is out of the frame and there is a lot of space on the left side and #33 emoji not being listed on the task list (even though no where on the instruction enforces that the only mentioned emojis to be strictly used and as well, even though the emoji itself isn't expressing an emotion directly but it does express it indirectly by implying that a person/task is perfect).

For the black and white bars you've mentioned, some of Tom and Jerry episodes were made including those pixel wide bars (maybe an issue they had in 1950s while making an animation) which don't degrade quality as you've said since they are difficult to even notice, hence becoming negligible for most users and also since it isn't used to manipulate the aspect ratio in any way.

Most comments are based on subjective evaluation which misses the objective points criteria to evaluate a particular GIF, which are:
1. Image Quality
2. Overall usability of the GIF and
3. Relevance for the chosen emoji.

You mentioned that there are two or more characters being in a GIF even though the emotion is expressed accurately to the GIF that is chosen but also was made sure that it will have a greater precedence than the other character that is in frame in case they are making an emotion (#97).

Another example that most of the comments you made are from a subjective point of view and I quote "#73. The gif is poorly done. Too simple animation. The black bar on the left side makes the quality worse.". You state here that the GIF was made poorly due to reasons that are not mentioned (I doubt it is in image quality because the image isn't blurry, pixelated or washed out but it may not be the very best. It is reasonably clear for the image to be clearly seen and understood by anyone.) but if it's because the animation is too simple then too simple doesn't mean poorly done. The GIF is simple enough and was cut preciously to make it seem as if Tom is crying infinitely without creating jittering.

To summarize I accept few criticisms that I have received, character is partially cut out of frame and a single GIF doesn't directly express emotion. Other than that, the rest are subjective and biased evaluations that don't follow the three main objective evaluating points. Again, I appreciate for taking time to check out my GIFs and give your input on it.
