just a suggestion.. if you want GOOD CC.. only post 2 or 3 images... and number them..
#1 is pretty typical..
#2 horizon is WAYYYYY off...i'm going to assume you mean to make the image go like that.. .angled pics have a place.. a picture of a barn is not one of them... not this close up anyway
#3 is cool, but i hate that post.. I would photoshop it out.. wrecks the pic
thats all i'll comment on i'll leave the other pics for other people
