Tower game asset

In my maze game that I have been creating I had decided to change the star which takes you to the next level to something that is more jungle like. With that in mind I designed a tower on photo shop which looks like it is crumbling.

Here is the finished piece:

I added details such as the broken windows and cracks in the brick to give it more of an ancient vibe. I also Added so different shades to the tower to give it more volume and look somewhat 3D.

 

This is what it looks like in game.
