Part of Celcus-by Shara

Last week, we got an assignment to re-draw an ancient Roman building..
I got a picture, but I didn't know exactly the name, but I though it must some part of Celcus, which is an old Roman library in Ephesus, old Greek town.
It takes only approximately 2hours to draw this, though I'm not able to draw the best because of I'm too tired.
Hopefully, I would get a satisfied score. ^^
