Tom, thanks. Yes, lighting would be crucial if I ever finish these. At the time, I didn't want to put too much time into them if the client wasn't going to pay for those views. So I presented them as "shells", no pretty stuff. But for portfolio sake, I'm going to revisit all of these drawings some day and finish/change them to the way I wanted them to be! LOL That's why I've come here to get advise and comments.
Thank you all soooo much. I'm actually getting a hankering to work on these again.... in my spare time, ha-ha-ha.
