Medieval Study

I can't believe I have created my first environment. This is what I have wanted to do for so long. It's taken a while to learn the software and be confident enough to try something like this. Unfortunately Blender 2.8 does not support my current graphics cards so the computer was very laggy and crashed many times while I tried to make this. Any feedback is welcome, I would love to hear what you think.
