I do not really understand what the caption is about. Those are okay, but very simple to replicate. The key to a good screenshot is uniqueness. Also, simplicity works well, but not too much simplicity. Anyway, if you understood that, 4/5
It's not a caption, whatever image hosting website he used added those when he copy and pasted the Code. And the pictures...really? Two sentinel beams and a Hornet
To be honest, the screenshots aren't good at all... What is the second one even of? All I can see is a horribly framed picture of the mancannons...
