Those two things are what got me with mine I made back in 2009. I had filled and shaded polygons, models with animations, and good framerate for the time, but then I ran into issues with z sorting and frustum culling in larger scenes. Still, was a great learning experience and I'm actually using some of the knowledge again for a retro game I'm working on.
