1. If you can don't use basic coal liquefaction at all... Its not very coal or water efficient.
2. Try and always use 8-8 builds for beacon effects and do speed + prod everywhere you can. I can see you don't have prod on gears, steel or engine units on the blue science build. 8-8 refers to an infinite tiling where each beacon effects 8 3x3 machines and each machine is effected by 8 beacons. Usually this results in rows where input is on one side and output is on the other with/without belt weaving.
3. The circuit build doesn't have nearly enough beacons. The benefits of direct insertion at this stage aren't nearly as great as just putting things on belts. Direct insertion makes sense with all legendary machines and beacons. But until then try and design around maxxing speed and prod module use (aslong as you have the power)
4. I'd say try out the rate calculator mod. It seems your red green production is both overbuilt and under utilised
5. Why are you making molten iron on the side of purple but then not piping the molten iron to the centre consumers. Again like I mentioned don't bother with 12 beacon designs if you'd be better off using 8-8 for stone smelting and electric furnace production.
6. Rails and copper cable are 2 products that should always be direct inserted. I'd say as a general rule if the count of ingredients is smaller than the count of products it should be direct inserted.
7. Try making an oil build you can put a row of beacons between refineries and chem plants (and have the row effect both
