Make a point of frequently going to art museums and sculpture gardens. Read the placards and learn to recognize certain artists, spend time looking at the pieces that grab your attention and think about them. Don't feel like you have to enjoy every piece. This will build your appreciation/understanding for two reasons:
1) Like all things, art depends on context. A piece is often in conversation with other works by the same artist, contemporaries, predecessors, or historical events.
2) Sculpture in particular depends on scale, perspective, and physical detail. You'll never get to appreciate these qualities through a photograph - you have to be there in person and walk around the sculpture. Look at it from different distances, different angles.
