WIP-London Bridge

Hi guys.
I started this to challenge myself. I know its better to start small projects and finish them rather then going for something over too complicated and not finishing but im hoping i can finish this one. I don’t know if i can model all the detail yet, maybe you guys could help along the way. Its suppose to be the London Bridge. I have uploaded the reference picture im using.
I saw a recent thread of a high detailed church, found here,(http://blenderartists.org/forum/showthread.php?t=104138) which led me to want to start something similar.
Think im being too over ambitious? lol, i do.
Anyway, started last night, here’s what i have so far? Should i continue or scrap it and stick to something more simple.


I think you should go for it. You have a good start.
