I'm not an artist, but they look fine to me. I am not the kind of person who spends hours in a Gallery admiring the nuances of paintings or photos. However, at the level of detail I usually admire these things, the clown one looked interesting and the Monalisa one was funny. The strawberry seemed a bit weird, but I don't think I'd care for it even if it was perfect anyway. The wintery landscape I thought was pretty good and the red dog it delivered what was asked. Not sure how it could be much different than that.
Well, most people who consume art are not professional artists. That was my main point. From the point of view of a lay person (such as I), it looks pretty good.
