Wow, thanks for making an effort to give me useful advice. I'm asking for helpful criticism that will be of use to me in the future. So unless you're going to give it, I'd rather you don't say anything.
If you would tell me what exactly makes them look like snapshots, then I wouldn't care.
One of the many definitions of 'critique' is "to review or analyze critically."
HoboSyke gave you their PERSONAL review of your photos.
I don't think there's any need to critque someones critque.
While I agree with HoboSyke on the style of your pictures I will offer some opinions of my own on how you could improve this batch.
#1. While it's a nice landscape there is really focus point that grabs the viewers attention.
#2. I would crop tighter and lose some of the wall on the right side. Maybe try black & white.
#3. While it's a very neat picture, I like how it shows motion, it seems there is really no focus again. I would've prefered for face to be in focus.
#4. I really like this picture also. But again, too much 'empty' space around the main subject. Tighter crop. I like color but I can also this in b&w too.
#5. I can see what you're trying to say here. Personally I'd fiddle with some effects in Photoshop or whatever editing program you have.
#6. I would erase the entire background and maybe make it black or something to look like a studio portrait. This is very simple to do, especially on this picture.
If you don't know how to do any of these things you can always ask. There's a section here about digital photography.
Remember, there are no stupid questions. The only thing stupid is to not ask. And you did ask for critque, no matter how harsh, so next time be prepared for WHATEVER anyone might say.
therwise, tell us to take it easy on you
There are other sections around here where you can post a picture and ask people to edit it themselves and repost. This will give you a better idea, visually, of what we all mean when you give advice.
Keep taking pictures!!!!
