Hiya noobie. Since you're new and almost completely worthless to models thus far, here are some good suggestions to help you along the way.
Before dealing with highly reflective backgrounds ( like water ) - I'd suggest somewhere that light is more obvious... and easy to play with ( areas of shade and soft lighting ). I can only guess that you're using a digital camera.... which is sad, because slide film can teach more than any digital.... but if it's all you've got... so be it. If all you have is an auto-mode camera - toss it in the drawer and forget it. First rule is that you MAKE images. Don't let the camera think for you. Turn whichever dial to " M " for Manual.
Next rule, bring the elements of the image you're after with you. Luck shots suck and models hate them. Come with an idea in mind. If the idea you're shooting includes clothing from Victoria's - don't buy a red fishing line teddy from Walmart... and so on and so forth. Think of what you want and THEN go after it.
God it's been a while since I've posted an image.
Don't be afraid to fail. It's better to set out on your own and FAIL than to shoot over someone else's shoulder and have the same fcuking shot as everyone else that was there... worse yet is to attempt to take credit from the shoulder you were shooting over. I call those people " Konica's " ( low rate copiers ) or just plain " Dumbshyts."
Now go fcuk something up and let us make fun of you for it.
