Personally I am a fan of strip boards, a hobby is to have as few cuttings as possible, or - alternatively - apply one cutting only over the whole board, easily accomplished with a rasp
So far I notice no wrong or missing connections. everything is nicely and efficiently laid out.
Row 6 should be labelled GND, as you have a connector there.
One suggestion: Give the LED at Pin 13 a jumper so you can switch it out when using that pin for a different purpose…
You could also provide a port for a low cost USB/TTL converter to easily plug in.
I am aware of three of them, their main issue beeing that they all have a different pin lay-out ;D
The extremely cheap chinese version (6 USD including shipping, CP2102) has:
(3V3) RST TXD RXD GND 5V (all male)
Note that RST already incorporates a differentiating capacitor!
The SparkFun version (twice that much, FT232) has:
GND CTS 5V TXO RXI DTR (all female)
Optional wires to a 6 pin ISP port will also be fine. By “optional” I mean that you need not provide them, but leave space and recomment a wiring.
