Hey Emmy. I wouldn't say you are a 'people pleaser' but I do know that if others are happy around you then you will be happy - that's how I was when I was planning my big day.
Maybe your mum is being blase about it all because she's sad to be 'losing' you. They say you take it out most on those closest to you (I certainly do with DH) and it sounds like she could be doing that with you. Maybe talking to her about the wedding makes her sad because her little girl is growing up?
You need to do what you want and what makes you happy - and if that is making sure your guests have a good time then so be it. Lawn games is a great idea, but I think you'll find that if you get Jenga that the adults will join in too, esp if it's out late and there are a few beers in people's hands!!! That happened at two summer weddings I went to - great laugh!
And you are not a drama queen for saying 'urgh' to a dress - you're the one who has to wear it all day after all so you goota like it!
OMG that last bridesmaid dress is AMAZING!!!! I love it and it would look beautiful is a summery yellow colour!
And you've got lovely shiney hair - love the photos! Are you going to wear a tiara? The only think I wold say is it would look great with a little bit of height (either hair or a tiara/flowers). The best advice I can give you on your hair is to make sure it is a day old after washing otherwise hair is too clean (mad I know, but important - I'm sure most hairdressers would agree). I'm a heated rollers kinda girl, but I have a stupid amount of hair so using tongs takes forever. Keep up the practice but I think you're doing really well!
