Photo Critic..

Solid work.

I would say the first one is the best in my opinion. I would consider the rule of thirds in that picture though, it would make it much more interesting to have the fountain bottom right with the lit structure & have negative space left of it.

The bike picture and person ones don't really do it for me. More snap shots than photographs if you know what I mean. You did use leading lines and DOF well with the tire though. The person picture is played, think about getting it from a different angle maybe wide angle below.

Hope that helps a little.

I agree with what he said^ except for the bike one - although my opinion is more of a layman's one than a professional's, I like the bike one and the depth of the image.  It really brings it to life for me; twas my favorite.

Sounds great!  Thanks for the tips!

i like the first one a lot. i agree with the first poster that you could have made it compositionally more interesting, but other than that, its nice! second one doesnt do much for me. the third is decent, but i would like it more if it was the same body position but the person facing you, and maybe take the picture from above, looking down at the face/arms, at a wide angle. something like that would look pretty cool.

Here's another one for criticing.

Some move so fast now adays, they forget what a great place we live in.
