Doesn’t look like a beginner works for me, you really have good design skill. If I may give opinion, the background of the content seems too white, it’s contrast with when I’m looking at header/footer, maybe adding a soft-texture/color will make it looks better, also the navigation menu on the top looks smaller compared with others and too right-aligned, and oh.. the text below slider seems like using a different font for itself?
Looks okay to me but check your footer text it looks like you have a rogue full stop in there (period).
Other than that the spacing is good, the slider looks pretty good – go for it.
