Great stuff! I did the boring umbrella plus hair light for
my first try
You probably overdid a bit with balancing though
as second picture shows. You *might* try using shadow/highlights tool in PS or curves in Photoshop to bring up shadow areas.
Then... composition in the first picture looks kinda weird to me. It'd be reasonable to leave more space to the left of her, might even sacrifice the space to the right (so that she's effectively on the
right side of the picture. That'd make more sense to me.
Then, you have dust on your sensor. 2nd picture
Your son ain't happy with that
Then, the last pic. They are staring at the empty space to the left of the picture that does not exist... This pic would probably look great if oriented horizontally, so that there's some more space to the left of them (even if it's just skies). Besides, you cut off your daughter's legs
That's what I can think of for now...
