The baby with the Santa hat – Where does the white fuzz end and begin in that photo? You’ve lost the detail in your highlights and you cannot see a defining line between the white parts of the hat and the background. There are also edges along the baby’s arms that are not tack sharp, the right arm fades into the background. Did you light the background? The white balance seems to be off as well.
Just a personal preference, I don’t like big fancy watermarks either, but like I said, that’s a personal preference. The font isn’t that hard to read but you do have to look at it to see that it says grinz. The font isn’t consistent either. In the first several photos you use one font, but with the baby you use a different font.
