You Adrian. I'm no sure how much you want to spend on a Camera, but check out used Rebels on BHPhoto. You can get a used Nikon D40 for $200 with a lens or a Rebel XSi for $230. It would up the quality of your pics and allow you to build a deeper following on a Blog. Now is the time young guru.
Agreed, since this is obviously something you enjoy doing and do regularly, I recommend you skip on a couple of suits since you have plenty to hold you up and buy a good canon camera with a 35L lense....that's all you would need...sure it's expensive, but you making pretty much responsibility free money, since you live at home with a good job...the pics are well composed but the quality does your fits very little justice bro...I think a big reason why some of my stuff has been featured is in part due to the quality of my shots....it makes a ton of difference....just my 2 cents.
