I did a redesign on a park once for a project, it wasn't very good but I've done a lot of research into landscape architecture. I do agree that there could be a stronger sense of continuity in the park and a way to integrate sections more, but I also appreciate that this just seems like a nice place to hang out, skating or otherwise. I like the trees, and natural elements, and the direction this is going looks pretty good. I think it would help inform some of your decision making in the layout if you research what makes a successful public space and then applying those principles to skateable components. But keep updating, I'd like to see how this develops.
