To me they all seem just like snapshots- in the second one, the bottom left is very underexposed whereas the top right seems to be correctly exposed sort of throwing off the balance of the picture. In the first one, there appears to be the same problem. Also, there is not a specific subject and nothing seems very sharp, making it not the most pleasing image to look at. The colors are a bit too warm for my taste and again on the second one there isn't a central or sharp subject. Then again, what do I know? I'm a beginner at this.
