So eh yeah, for my art class and college portfolio thing, I have to make atleast 3 architecture pieces drawn from realistic things (so from real examples of buildings), and so I used picture references from buildings that my friend took while she was in Chicago visiting colleges 'nd stuff. Each one of these took about 4-7 hours to complete.
One thing I will mention though, perspective is one of my weakest areas, so if you examine the pictures close enough, you will find small mistakes in the perspective and angles.
Oh and just ignore the little labels at the bottom right, that's just something I had to do.
^ "Apartments"
^ "Buildings in Chinatown"
^ "Old Church"
This is also something I finished quite a while back, but it's one of my favorite things i've drawn thus far in art class, and I think the title fits..
^ "Screwed"
I might post some of my other finished work at some point..
