I've gotten a good amount of work done on the MDF pawn shop I posted about last time since Friday, and have probably one or two more sessions to go to finish the building proper; resin and MDF furniture will be another session or two on top of that, in all likelihood.
The original red spray paint I bought to do the doors, window frames and signage in ended up being a weird neon red-orange that wasn't what I was looking for, so I painted over all that with ordinary red craft paint. Everything was given a light drybrush of a pale tan to weather and dull down the brightness of the red. I've glued in the back door, it's frame, and the window frames, plus used pieces of acetate sheet to make window panes; I've glued them in because I want to varnish over them, which will make them frost and look dingy and unwashed. The front door frame is test-fit and sanded, but not yet glued into place. The furniture inside has been assembled, but is not glued down because I'm going to hit it all with a can of black spray paint and then just give it a little drybrush to help the edges pop. There's a few resin bits and bobs I'm waiting to come in the mail as well.

Around the side of the building, I've applied a graffiti decal - I bought a couple sheets of these off a seller on ebay; they're designed for model railroaders to add realistic graffiti to train cars, but O-Scale is close enough to 28mm for my purposes. This one worked really well; I was nervous about it tearing during application but it went on like a breeze. I've got a dozen more designs, and I'm anticipating using maybe one per building at most as I grow my modern terrain collection.
The colors are really crisp and bright; I'll probably apply a very light drybrush of the tan over it to weather it and tie it into the wall behind it a little more.
In addition to this, I started doing a little bit of work on my next building. One thing I regret not doing more of with the pawn shop is sanding down the lugs on the pieces; the fit on everything is exceptionally tight and once you add a skin of paint over it, almost impossible to get the lugs into their slots. So for the next building - a blank storefront that I'm building as the "Fat Dragon Self-Service Ramen Eatery" - I'm starting off by sanding all the lugs down!
The furnishings are from OSHIRO Model Terrain - there are two noodle vending machines, a drinks vending machine, recycling bin and (not super visible by the front door) an ATM. I'm waiting on a set of booth seats from Miniature Building Authority to finish off the furniture collection for this one. The exterior is going to be the same color as the pawn shop, but I'm thinking a light blue for the interior walls. Flooring is going to be the same wooden plank pattern I used for the pawn shop.
I'm debating if I want to do some flower pots on the sidewalk under the window and next to the front door.
I'm hoping, given the lessons learned on the pawn shop, that the ramen eatery goes even faster!
