Welcome to the community djm!
I don't really know much Portuguese (except "Ishta un bon dia") (Not even sure if that's spelled right, but that's how I say it occasionally). With tools like Google Translate and such, its pretty easy for those who browse only in English to read it, but you'd probably get more views/hits with English writing too I'd imagine. I DO love your pictures though, very nicely done and formatted!
Either way though, I look forward to seeing your collection! Let me know if you've got any questions - there's plenty of people around here who are happy to help out!
