Compressing a GIF
I need to compress a GIF

As of the recent, I started learning to work with adobe after effects. Naturally, I've set myself a goal to make an animated GIF "Artwork" for my steam profile. The hard part, ironically, was not so much making the GIF itself, but rather compressing it to a suitable size of 8 MB and that without major loss. After doing some research on this topic, I made the whole project colored in similar colors and removed some of the animations (e.g. fog). After rendering scaled down with Adobe After Effects, the GIF now is 33.7 MB big. Are there any tips on what I can do to further reduce the size of the file (on the image, there are 6 tiny spots with colors starkly differing from the main color range. Would changing those to a similar color range make a big difference)? Is there any optimizing/compressing software anyone could recommend?

P.S. As mentioned before, I have Adobe After Effects and I also have Adobe Photoshop and Adobe Media Encoder.

Thanks in advance

Post in the Adobe forums.
Here some key things to know about. I don't use after effects, I use Photoshop.

Make your gif big as you like, afterwards you will be downsizing the whole thing, since you already made your gif, simply downsize your gif, shrink the resolution, this has major role on affecting your file size, another is deleting every other frame when you redo the gif, as long you keep your gif how you like it looking smooth enough to look at, this can cut down your file size as well, and last is optional, but can affect your image size is limit range of colours when you render the gif.

I already said that I scaled the GIF down, hence the file is only 33.7 MB. Regarding the removal of frames - is there a way to do that in After Effects? If so, how?

P.S. You don't need to repeat that limiting the range of colours will help, I was asking whether the difference in file size will be noticeable or not.
I don't use AF, only photoshop.

You can put it into your Adobe Photoshop, delete every other frame, and review the work.

Limited the colour range may, or may not be noticeable depend how many colour range you used.

How big is this gif btw? Can you show us? Use Imgur and post in the discussion.

I was wondering whether the size of the GIF depends on the variety of colors, or the amount of differently colored pixels

Another problem is, I can't upload the GIF anywhere. On most sites (incl. Imgur), it takes about 10 minutes to load and then just shows an error message and on some it won't upload at all.
Like how long the duration of this gif???

And I upload loads of large gifs on Imgur, they normally get converted to MP4 if it's too large.

If can't upload this, tell me what the resolution of this?

it's 6.3s

I'm doing it with Photoshop right now, but when I try to import the GIF to the timeline, I only see half the frames and it looks like it moves at 50% speed. Any ideas what the problem might be?
Half the frames? Saying the whole thing isn't loaded into the timeline?
50% speed? Check the delay?

Also what's the resolution of it?

Setting the delay on all the frames to 0 didn't change anything :/

Alright I see the one you have it 15MB, also delete one every other frame, should take you down to 72 frames out of your 143. Let me know how far it goes down for file size.
Dude.

The problem is not that I can't delete it. But that the GIF is imported incompletely in photoshop. Please look carefully
If you want I edit your gif, just upload a copy to like dropbox or something, and I edit it for you if you want, and show you how it's done with examples, do note I be back in about 2hrs so up to you.
All I need is for someone to explain to me why Photoshop doesn't show the whole GIF on the Timeline.
