People will give you more feedback if you post images of the board rather than zip files.
Why the massive transistors for a couple of LEDs? You could use SMD or TO-92 devices.
I don't see anywhere for power to enter your board.
There's a common connector for the switches but it does not go anywhere (touch pads maybe)?
When laying out a 2-layer board, stick with a convention with top traces in one direction and bottom traces in the other.
Then you are less likely to corner yourself. Do the power rails first, and add a power decoupling cap near the logic device (since we do not know anything about the power supply to the board).
Unterminated inputs on the logic device should be avoided.
Thank you sir Geoff,
Take a look my feedbackQuoteWhy the massive transistors for a couple of LEDs? You could use SMD or TO-92 devices.Yes, well noticed the fact. I dont have any SMD type transistor decal.
Can you give it to me ? What I have is attached.
Yes, we can also make it our own.QuoteI don't see anywhere for power to enter your board.
There's a common connector for the switches but it does not go anywhere (touch pads maybe)?Can I use a 2 pin connector here for power? What about SIP-2P decal?
QuoteWhen laying out a 2-layer board, stick with a convention with top traces in one direction and bottom traces in the other.Dont you mean in layer defination , TOP and BOT can be set to Horizontal and vertical?

Lets assume decoupling capacitor stay at external PS.
Isn't the common pin (pin 2) of the switches supposed to be connected to VCC?
Yes, that would work fine. Hopefully you can sort out what your switches are supposed to be doing.
No, I mean when routing. I assume you routed this simple board manually. It would be crazy to use an autorouter on it.
No. You need to terminate the unused logic input correctly.
Let's not. That defeats the purpose of decoupling caps.
Stop building things and go to read some books. If you happen to be in a university, go to ask professors.
You need a LOT of things to learn.
First, where is power input? Where do you plan to bring your 5V and GND into the system?
Second, as I said before, if you want to set logic input level high when button is pressed, you need to tie the switch to VCC, so as the user presses the button, it conducts electricity and sets logic level high. When use releases button, the pull down resistor sets logic input lo
In a no ground plane design, run a thick wire beneath the chip from GND to VCC, and connect to the VCC capacitor.
I took a quick stab at it, and apart from your bullseye SPST pads I don't see a hard need for vias other than to connect to a solid bottom ground plane. (The switches will need a pull up, and 33ohm is too big for a pull down, but maybe I misread the tiny print.) The component designators don't match yours, but I just wanted to demonstrate it's pretty easy to route this. I didn't have bullseye pads on hand (and wouldn't personally use them anyway).
To note on your layout, it looks like the diode silkscreen orientation is the reverse of the A/K pins.
You can swap units in the 'LS32 to use different pins.
You can replace the transistors with a different jellybean device in TO-92 or whatever that works as well for switching but have a more convenient EBC pinout, if that helps. Or a dual device in a small SOT package.
You don't have power supply pins (I added those or it wouldn't ERC/DRC).

But which design tool you have used?
