Thanks for the reply and no worries, my bicep is healing quite a bit faster than anticipated.
I almost see no need for you to add any of the extra items to any of your current sets, as I think your current sets stand on their own quite well, maybe add a hallways extras pack… I would buy it.
One more question, do you have any triangle pieces planed? Thought about the angled/elbow request and realized that if I had 2 large triangular pieces to shift the angle to 45 degrees than that would as well and reduce mesh count. Also that may be much easier to incorporate into the feel of your sets then adding curves. Also with the addition of triangles we could make hexagons and Octagons which would increase the usability of your sets extensively (well for my project anyway).
Keep up the awesome work.
Happy Holidays
