Welcome along Cindy. What I can see of your guitar looks good. One thing to keep in mind is that a very small change at the point where the neck meets the body can make a significant change at the nut. Given you are talking not much in terms of a great action, it really wont take much to get it spot on.
Very worst case you would be looking at a shim (small bit of wood / paper that you can use to adjust the neck angle). That said, I haven't built a guitar yet that needed one (up to 5 done now).
On second look at the photo, I'd be tempted to check the two screws on the body side (as opposed to the neck side) of the neck. If they can tighten slightly that may fix the neck angle completely. Just need to be careful not to over tighten and shear the screws (have seen one person do this).
