Im literally planning this wedding alone. No friends. No family. Not that I care, but it just makes it quite difficult ya know? And my husband thinks itll be perfect no matter what I do so he's not much help, lol. First off, I just have some questions and would like to see what you ladies think!

First two pics...should I do an arch like the one in the background of the first picture or a unity circle? and if I do a unity circle, should I do it out of rose petals or sea shells? And second, I was thinking of doing the aisle runner out of white rose petals. Densely put on each side to make the aisle with the tan and blue and white candles thrown in there and 3 diy candle bowls like pictured below. As well as some small sea shells thrown on top of the rose petals and maybe a few scattered down the aisle. Too much or tacky? Or okay? I hope I explained this well enough. Its so hard to explain to someone whats in my head and if I can't physically see it...I have such a hard time deciding. Any advice would be appreciated. Thank you ladies.
