Looks great
Since its your first site please take note of the following.
Does your install directory still exist? If so your site is vulnerable to hacking
Are you using and WYSIWYG editors other than the recommended FCKEditor?
I agree with you on WB being great for smaller sites but I am launching a site soon running on a heavily modded version of WB that will serve over 1000 pages. I also have an intranet running on a slightly modded version of WB and again its a huge site.
Keep baking.
