Medieval Castle (Second Draft)

This is my second draft for my medieval castle. As you can see, I added the outer wall for the castle. I also added towers and a keep for the outer wall. The big cylinder like the towers, it is the keep or dungeon.There will be other things made later in the castle such as the drawbridge with portcullis,chapel, stables, watch tower, battice a stairs. I tried to be creative for the towers, try to make it look fancy or something like that. But unfortunately I made it looking so simple because then I feel it is just easier for me to do it that way. So I was thinking to make the keep the same design as the other towers in the outer wall of the castle.
