Hello Melanie,
Your work is stunning.
My suggestion (to add to all the great ones others have mentioned) is to perhaps steer away from the idea that children are cute. For me, I find them exceedingly more interesting than MOST adults because they are honest, they are wise, and much more authentic than adults give them credit for. I try to see them without the filter that parents like to color them with.
The flip side is that you won't appeal to MOST people this way. You will fit in a different kind of market that will present itself to you in time. Parents like to think of their children as adorable (and they are) instead of deep(which can come across as sad). But, I have found that sticking to my guns has brought me clients that believe in what I do, and do not second guess my vision. I'm so grateful for that!
What worked for me was the website, and charity auctions. Shows, awards did nothing and just stressed me out so now I avoid them at all costs.
Just my humble opinion. Best of luck
Regards,
Stanka
