you MUST NOT have that giant signature/watermark - they will not print it. i assume you want to be critiqued, that's how i read it... this image has that flower on the left that is out of crop and it's not that sharp. it's actually a very busy scene kind of cluttered. there are too many flowers on this site. so whatever you have it has to be something special.
you don't want frames on things, they don't look good and not everyone wants a thick black border. again the signature - has to go. you can make it much smaller and place it on the bottom. but they won't print this as it is. how many images in your house has a huge name? put more tags in, but leave out nebraska. since this has nothing to do with that state and it only confuses the search, do add your own name.
its nice, a bit dark, you know about the name already. it's not really in focus though, and they may complain about that alone.
this is rather hard to read. the words are too close together, and the background and thinness of the font makes it that much harder. it also limits how many want it. its the only one that doesn't have your name though so that's good. you need more keywords.
you'll want a better description for this. i don't know why anyone would want a feather for a wall. and it has that frame and odd effects to it. you'll have to figure out who these are for and market to those people. it will be hard to sell a partly out of focus feather.
adding the thought that your name will be on that print - won't make it sell better. its an ok scene, but its hard to know what i'm looking at. it's mostly sky. it's also rather noisy and it won't print because of that. again very few keywords, i assume that's at least a farm? that should be added.
your bio is very wordy, it's often best to keep it simple and to the point. don't make people leave to facebook because they won't be back and they will forget where they were. family life, who should have it, the speech about public domain, i would leave that out, it makes it look less professional. you can have a simple copyright at the bottom.
