Can some professionals give me some tips? On my photos?

Http://www.facebook.com/pages/Jesse-Bartelds-Photography/301798969857692

I'm only 17 years old and plan on doing photography as a career. I hardly edit my photos, and I own a Nikon D90

Thanks in advance!

Added (1). I have only been doing this for less than a year, so I'm not considering myself a professional for a while, I really want to improve. And I hope by the end of the summer to purchase a Nikon D200

Camera? I'm taking my own senior pictures?

I don't want someone else to do it so that i can go to a lot of different places and change my clothes more. I'm thinking about getting a nikon d100 6mp digital SLR camera. But suggestions would be appreciated.

Good Price for Nikon Set-Up?

Nikon D200 body + grip (don't know if it's original of aftermarket… )
SB-800
SB-24
Nikon 70-300 AF-G
Nikon 50mm f/1.8
Nikon 24mm f/2.8
Tamron 17-50 f/2.8

Also extras such as battery, charger, shutter release cord, Tamrac Pro bag, stand for SB-800, CF cards.

They are asking $1000 obo.
Is this a good price for a nice set of good working equipment?
If not, what's an ideal obo price I could offer?

Which Kipbling bags can carry a large camera?

Hi, I need a bag to carry my Nikon D300, I have a normal camera bag, but it's quite ugly and very uncomfortable to carry. Then I noticed these Kipling bags and I really want one for my camera, but does anyone know any bags where the camera can be in, because I've noticed most of their bags are small.

Should i go for a combo or just one Pro DSLR?

Should i go for a combo the nikon D800 and a D4 or a Canon Eos 1Dx i don't have any lens from nether i will get a loan to start a photography business and shoot wedding and sports.

Added (1). I have a Sony i want to upgrade to a Nikon or Canon i use to shoot for a news paper company i no longer do that, so can some one help me decide i don't know which to get…

Added (2). Then what's the best combo for the 1dx?

Setup multiple camera flash to fire individually?

I just about to buy a new nikon d800 and 3 flashes, I have discovered that the nikon sb-910 can act as a commander for other flashes such as the sb-700s so my plan is to get one sb-910 and 2x sb-700…
What I would really like to do is set up a rig so that I can shoot 3 photos in quick succession using different flashes.e. G photo 1 - flash A, photo 2 flash B… Etc.
I can't find any information suggesting the rb-900 can do this kind of thing without manually cancelling and enabling flashes,
does anyone know if it can?
Does anyone know another way in which I may do this?
I guess my budget is about £800 - £1000…

Light painting with a Nikon d300?

I'm supposed to do a light painting for photography but it's just not working for me. I have the shutter speed set and a completely dark place, after I move the flashlight around, the picture turns out as just a very dimly lit version of the area. Does anyone know what I could possibly be doing wrong?
