Hello, as you may know I am new here and I have little knowledge of electronics as I am learning. Could you take a look at this schematic and see if you see anything wrong with it. I am especially concerned with the current. Do I have enough? What about all the Vccs of the ics?

I think that is it except for more ordinary parts like resistors and capacitors
Any help at all would be appreciated please explain thoroughly as I am new to this. Note: any labels are what i think will happen not necessarily what will.
