I don't see anything there just yet that says to me you are ready to be making money from photography, but the first step on that ladder IMO is asking for critique... Too many people think they are great when in fact they are just yet another person with a camera, but those who look for peer review (and listen) become the better photographers
So firstly what do you want to make money from? Your portfolio is quite non descript in regards its not pin pointed a particular genre IMO. Personally I focused on people from that start and worked out what sub categories of 'people photography' I loved and worked VERY hard on becoming good in those areas (portrait & weddings). I don't see that focus in your work and think that's your next step... Look at magazines and websites and think 'I want to take that shot' and then work on the skills it takes to replicate what makes it work so well for the published photographer.
The critique section is wonderful for getting feedback from highly competent photographers who can help you improved on all aspects of your shots so
start posting in there with your best shots... And remember even it's hard to take their advice will always be helpful and make you improve and learn new skills and tricks
Hope that helps
