This looks a nice model, but I would like to suggest a couple of things to make this much better and visually more interesting.
The statue looks very shiney and new and this may be the look you wanted but visually its uninspired. Personally I would weather it a bit by chamfering off those sharp edges as if the rain over the years has worn the edges away. Maybe add some damage such as some chips off the corners and if you want to go nuts maybe some ivy or other such plant climbing up it.
I dont use blender myself so unfortunatly I cant help you out much but have a look for some tutorials to help bring this model to life. Good luck
