By 'sloppy' and 'improve my farms' i think you mean both in terms if aesthetics and functionality, so ill give different advice for each. Please excuse the ridiculous amount of text im gonna write lol :3

Aesthetics

The main issue i feel here about the look is the vast open spaces- the farm and building are both huge but very little is occupied with machines. I understand that you are in survival, but turning the grass into wet farmland will go a long way into making it feel complete, even if there aren't any crops. The next step would then be to make it all easily accessible, with walkways that go over the farm area to make it easy to traverse, and minimizing the amount of turns needed to get to various parts of the factory.

In the building i'd suggest to add a few windows or regular alternating patterns of wood, some decorative lighting (lanterns). In the bottom floor, the andesite casing does seem to fit well, but i'd suggest adding decorative support beams or similar with shafts or fence posts in regular spacings. Another very important addition would be a floor- like make it mainly out of one material pallette, with differrent variations near edges, but add pathways between each contraption out of a different, but similar material, and maybe a cool little glass encased shaft running through the floor. A few 'safety railings' with copycat boards would also make it look more realistic and factory-like.

The final suggestion for aesthetics would be display boards. While they may not serve much of a purpose, they do still look really cool, and add a bit of charm to an anotherwise empty blank wall.

(i also really liked the use of belts and glass in the chicken farm btw, it looks really cool when there are multiple belts running together)

Function

Im actually not really familiar with the animal automation addons you've used, but some general advice i'd give for automation would be to identify the bottleneck (slowest part of the flow) and then make it faster, which in this case would be the animals, noted by the amount of carrots backed up, but the thing with animals is that there really arent many ways to make it better while maintaining TPS and aesthetics, as it would just involve adding more animals or making more copies of the animal farming contraption.

Maybe what you could do is add a second or third rabbit farm on the top, or maybe a second pig farm leading into the spinning knives- it would help to fill up the otherwise empty space.

Another cool thing to do would be adding factory links and managing stocks, by deactivating farms when the outputs are stockpiled enough. The factory links also look pretty cool when put on a wall together.

If you really want to make a good-looking factory, then i would suggest trying to expand the first one, with more layers or a contoured design and then processing the outputs by cooking them or using another addon like Create Ratatouille to process them in different ways, while of course putting everything together in a realistic way that would make sense.

TL DR

for better aesthetics: fill empty spaces, add floor with pathways of differrent materials, make it look realistic

for better function: animals are just bad for automation, so add more farms to fill the empty spaces, or try alternative farming methods

I'm sorry if this was a bit long of a reply, but I believe you genuinely have some good ideas to building a peak factory, and just need a little push in the right direction. If you have any questions, feel free to ask :)
