BHI,
Welcome!
The quality is there,technically and the images are fine as they are. I think I would suggest that if your purpose is to sell and COMPETE here, I would spend some time on research and see what is selling. And then make an honest decision whether to invest in becoming a "member"($30) or stay under 25 images and just have a presence here.
If you just want to post photos for friends and family, then this is a good place, but there are many others, for free. There are many great sites,where you can post your images and get feedback etc., if that is your purpose.
There are many really,really good artists here and that's your competition and that ain't easy!
Just for fun, go see my stuff and after a few years, I'm still struggling to get sales. And I'm not in that "really,really" good group either!
Let us know what you're really asking here and if we can help, we'll certainly join in! There is a really good group of folks here, with a ton of experience and love to share it,
Good Luck,
Rich Franco
