you "could" make money....yes.... eventually one day. while thes aren't bad, they arent purchase worthy (IMO) but the good thing is that shots like these have potential. Try shooting a bunch for free as practice and then when you're confident enough, start charging. Looks like you have a great eye, keep up the good work and experiment with new lighting, background, and posing!
Just a personal preference, but I HATE HATE HATE seeing "portraits" with kids and their pacifiers. Taking a quick shot of baby playing with toys and he has his paci... no problem. but PLEASE parents, if your mission is to take quality portraits of babies and kids please take the paci out of their mouths....
