The Quezon Memorial Shrine is a monument and national shrine dedicated to former Philippine President Manuel Quezon located within the grounds of Quezon Memorial Circle, Philippines
Coming from the Philippines, it’s nice to see some showcases based there! I think if you included comparison images to this post it would be nice to compare to your build, but the shrine itself looks good!
However, if you are trying to go for a realistic showcase, I have a suggestion.
You could change the lighting to make it look more realistic. It could nice to have sun rays shine through the shine as the sun sets.
You could also add more plants in the tree areas to give a little more life to it.
Other than that, it looks good and I’ll remember to visit it later!
