It's amazing how some people just have that... that.. certain something that can turn an "ordinary" fish (bettas are anything but ordinary) into a work of art with shadows being cast and light illuminating spots you never even noticed. It's a true talent, and I wish you the best of luck in pursuing it. :)
Well, I don't think I would know the difference between you and a professional. Of course I don't know much (or anything) about photography besides the fact that you need a camera to do it. But even I can tell, you're photography is something special. :)
Did you take those pictures of your bettas and pets? Wow!!! You're a great photographer! Wish you lived in my area. With those quality pics you could start a photography business! They're all gorgeous!
