Building McGee's Hotel by Micro-scale Models again Pt.2

I am one step closer to achieving black belt in Micro-scale kit building. So far I have made four of them and few more are coming in the nearest future. I even acquired one myself recently and have my eye on few more - new waterfront series in particular.
Building McGee's this time around was much easier. I knew what to expect and all hardest parts of the process. For example, I didn't use "L" shaped stripwood for small addition corners. I trimmed the wall pieces instead and used 1/16th stripwood. Also I didn't use provided in the kit tarpaper roofing material. Instead I used thinner painter's masking paper. All that said, I still had a little trouble figuring out how all those angled roof pieces come together. As you can see in the pictures, they did but it took me two tries.
On another note, quite few people have been telling me how I should try gator foam for my diorama bases. I have researched few possible options, but none of them have turned out to be very attractive. I either had to buy large quantity, or incur relatively high shipping cost. As was still weighing my options, on the way home from work I spotted a sign shop. The gator foam is used primarily for sign making, so I stopped by and asked if they had any leftovers. Guess what? I am proud owner of one 2 ft. by 4 ft. piece and two small ones! Also I paid very reasonable price.
