I started out in a low-wing airplane. When I finally got checked out in a 172, I couldn't believe the difference between the ground effect I got from the low wing and the lack thereof from the high wing. In the low wing, I didn't really have to do a lot to round out and flare. The ground effect helped a lot. My first 5 landings in a 172 were borderline dangerous. I kept giving it the same nominal effort, with almost disastrous results. Of course, I only had 40 hours at the time, so lack of experience may have played into it. You have plenty of time, and although the first one may not be pretty, I think you'll do fine. One more thing, I always felt like high-wing airplanes were more stable.
