firstly, your work is amazing, true inspiration towards lego building brilliance.
these questions are probably meant for another forum, but you appear to be the sort of man who can answer my questions - you'll have to excuse my ignorance, (i am only just rediscovering my lego building skills after 20years absence from my childhood days) but where can you get a hold of all those different coloured bricks? LDD is a bit restricting, as it will only offer certain parts in specific colours.
my next question is i am a reformed architect obsessed with facades, so my lego creations are usually facade-only, but what's the common building technique, do most people usually put a back to their buildings? i notice most of your works have lift-off levels for internal access. should i change my technique now before it's too late, or are there others out there who build like me?
attached is a screen-shot of a recent design of mine for your advice/feedback, based on a picture of the tibbits opera house (link to the image i based it on here ) a lot of the bricks have changed since my younger days, so i am still getting used to creating some of the finer architectural details.
