Just a comments on your schematic. There's a lot of redundant stuff put on there, big labels, pretty pictures of random parts, but you haven't labeled some of the stuff that's actually going to be really useful when you're sitting at the bench with this thing and the schematic. Stuff like the reference voltage, you've put a redundant comment below the voltage reference stating it's part number, when the part is already labeled, but you haven't put down what it's output voltage and tolerance is. It means if I were building this, or debugging it, I'd have to go off and get the datasheet just to check if the reference was outputting the right voltage.
Many times on this forum people criticize connecting together a schematic with net labels, and yes I'm not a fan either. But if you are going to, don't have vertical labels on connecting nets, they're 10x harder to find. Also where reasonable, put inputs on the left and outputs on the right, it's just how most people read. E.g. the connector for the ADC has no reason to be in a rotated orientation, you've got plenty of room on the page, so move some things around and place it on the left of the block with the net labels facing to the right. Now it will automatically look like an input connector adjoining to those nets. Now, even better, fix up those ADC input filters buy putting the grounds facing down (don't face grounds vertically), and arrange them such that you can connect it directly to the connector without using net labels. This block would be much easier to understand and look a lot more professional.
