Default Lm723 - 19vdc In, 14,4vdc Out

Hi all!

I tried to make a simple design based on the LM723 datasheet, without sucess so far, because I have almost no knowledge in electronics projeting.
I would like to make it voltage-dropouts-proof, with a PNP pass transistor and also to try to use as few components as possible.

I've attached a image of the circuit. Any suggestions are welcome!

VIN: 19VDC
VOUT: 14,4VDC

Thanks for the attention and best regards!

I've redrawn it and now it seems to be working pretty nicely at Multisim.
Do you guys have any remark for me before I build it?

Thanks for the attention!
Daniel
