teen devil, you ask us if the circuit does what you want?
I suppose you have some specifications - and we know nothing about it.

Why this question? Do you expect any errors?
In this context, just one comment: It is not easy to read the circuit diagram as you have chosen a kind of wiring (very unusual) which is very difficult to verify (many wire crossings and complicated connection between parts).
