After research, I've found a lot of different sub-style of Victorian architecture. Which one are you interrested in? So far, I've found Eastlake, Neo Gothic, Queen Anne and 2nd Empire.
Thank you for your nice comment, it's really encouraging ^^. I'm planning to make more architectural/city and interior oriented packs in the future. The Victorian style would be interresting to create in the style. I take note!
