Hi, Dexter! A fellow Olympus user here :) (although not the same model)
A lot of my thoughts have already been covered in previous comments, but here are my opinions anyway.
You managed to get a nice pose/expression out of him regardless of his (im)patience, it seems. It's that very 'huh what's going on?' look that babies have, infinitely curious and confused.
When you mentioned that you cropped the image, did you accidentally crop out the tips of his toes, or were those not in the original picture, either? I understand infants can be tough to work with as models, but maybe if you had positioned yourself further away you would have been able to get a complete shot of him without slicing off any digits. I don't quite agree with such a tight crop, either...because his pose isn't the most ideal for a tight crop (it's rather unbalanced), if you had left more negative space around him it would be more effective.
Also, it looks like you used your camera's built-in flash...for portrait-type shots like this it's a better idea to nix the flash and use external lighting instead. My suggestion (and my own personal technique) is to get a desk lamp, cover it with a sheet of paper, and use that for lighting instead. That way the lighting won't come out as flat or harsh. It might also help with some of the noise issues because the lighting will be more even.
A lighter background would definitely help, especially if you smooth it out more. I bet he probably moved around and wrinkled up your backdrop anyway, but it would look less obvious with a lighter color. Also, the dark background matched with the tight crop kind of gives the impression that he's lying in a narrow, dark cave (not the greatest analogy, but I think you'll understand). It feels less like a fashion ad and more like an "I'm afraid of the dark" shot.
Anyway, good luck and I'm sure you'll have many more pictures of your son in the future :)
