Timișoara Orthodox Cathedral

I'm not a illustrator, but always admire people who can do this kind of drawings. Wanted to try this thing for a long time, but never had the chance, so today i finally did it and try to make one of my town iconic building, it's the Orthodox Cathedral in the city of Timisoara. More about the monument here: http://en.wikipedia.org/wiki/Timișoara_Orthodox_Cathedral

I know that the drawing doesn't respect all the details, but it reflects my approach and i'm happy with the result so far. What do you guys think ?
