You got some good photos there just try to pay a bit more attention to your composition as to try to avoid cropping out body parts such as limbs and parts of the face. I think you did a smart thing by buying the body only to avoid the kit lens to save for one of better quality. You can't beat the nifty fifty for its price. Its build quality is far from the best but its image quality is surprisingly good for a lens of its speed. At f/4 and smaller it is pretty darn sharp, wide open it is soft but it is a great portrait and landscape lens. Its slow, noisy autofocus makes it not so great for getting shots of fast moving subjects and in low light situations the AF seems to hunt a lot making it a bit of a pain but when it does focus its large aperture makes a big difference in the low light conditions. The cheap, 5-blade aperture can also cause some interesting and even distracting bokeh if you're not careful.
That being said it is a great lens for the money and can take some great photos
