I'm not affraid if they were to show them to a professional photographer.
If anything it'd be great to hear their honest opnion. When I photograph people I make it crystal clear that I am brand new. I do not lie or sugar coat it. I flat out say I am a newbie I worked on my portfolio for a year and want to expand my portfolio. This is why I offer folks free sitting fees. and charge very very very little for the prints they order. I order them from a site I like not a typical walmart, cvs, walgreens etc.. etc.. I explain to them that
I know I have a lot to learn and I am not perfect and never will say I am.
I strive to get what they want and we talk in great much of exactly what they want out of me and out of the pictures I take. I know probably none of my photos are perfect to you professional photographers but like someone else said I
do capture that moment that they will remember for ever and
work like all hell to make that picture more perfect. I am a newbie and
have a lot to learn but I'm one determined S O B and will get it eventually
I like to do portraits, families, kids, animals etc. If I can capture that typical Goofy loook my friend Carrie's horse ALWAYS does in a picture which captures his attitude, his awesome appy spots and that spunky look of life he always shows and she's happy then I'm happy she's happy.
Everyone always has room to learn

One of the best things of life, I must say
It seems to me that you are looking for people to help you justify your selling your photos as an amateur, rather than really asking our opinion on anything. And when you aren't getting the reinforcement from us, you are providing it for yourself. I could be wrong, but that's the vibe I'm getting.
Trust me, you aren't the first to do that here. It's an all but daily occurance
Do whatever you want, but remember these key things......
It takes a lot of learning and hard work to produce professional quality photos. I'm not certain exactly how much because I haven't acheived it yet. Maybe someday, but not yet.
It takes almost no time at all for anyone with even a modicum of photography knowledge to point out exactly how and why a photograph was taken by a rank amateur.
Personally it would kill me (and understandibly any repeat business) if someone were to make my "client" feel silly for paying for an inferior photograph (why I don't charge yet). And trust me when I say this...... Be it photography, car repair, decorating etc. all it take is one time for this to happen to lose a paying client forever. Just one time. Friend or not.
From one amateur to another...... stop justifying, and start learning. I'm not trying to sound like a complete douchebag here, I'm actually trying to help. Take it for what it's worth.
