I think she does a great job of bringing attention to her initiatives. I would say most of her initiatives have only had minor success though. However, I think a large part of this is because the type of change she is trying to effect is frankly not going to happen overnight. Perhaps, in 5-10 years down the line, or longer we can judge her better. I do agree the Madrasti initiative seems to have been going well so far though.
Personally, as far as her 'image' clothing and such is concerned. I personally see it in positive light. I don't know why people always assume spending money on designer clothing and humanitarian work can't go hand in hand. Yes, if its excessive maybe, and perhaps in the Queen's case it might be. However, in my own personal case I spend everyday genuinely trying to improve people's lives - yet I also enjoy buying designer things and presenting myself in an elegant manner. Obviously, I'm not spending as much as the Queen and am not a political figure but the two sides of a person can completely co-exist. Why is it a crime to get enjoyment out of dressing yourself? If you really do spend most of your days trying to improve other people's lives?
And from a Muslim American standpoint - I think Queen Rania's image helps draw more attention to her causes. Frankly, if she wore hijab and wasn't glamorous (which has absolutely nothing wrong with and is commendable) many people would not know who she is and pay no attention to her. In many ways, her dress sense while extravagant in some strange way makes her more relatable to westerners. I personally know, people who got interested in her initially because she was beautiful, elegant, well spoken, and fantastically dressed. As a result many started listening to her speeches, interviews and youtube videos about trying to breakdown arabic sterotypes. Many people feel they've learned a lot from her. So, while I understand Jordanians might be upset she spends so much time abroad and not paying as much attention to their causes as they'd like, she has been a fairly substantial influence as a Muslim Woman in many other parts of the world.
