let me know what you think
Green door:
Really doesn't do anything for me. The wood has a nice texture, but the composition is bland and there aren't any really good lines to look at, plus the sign just keeps my eye in a boring place.
Portrait:
Nicely done. I'm generally not a fan of low catchlights, but the exposure is spot on for a white shirt, she's got a good smile, relaxed pose and the overall scene balances well. I'd tone down the white blob on the left in PS.
Canyon:
I'd probably have gone with more sky, but I'm assuming you wanted the little people in the bottom of the shot for scale? It's a good, but I don't think great treatment. I'm with epicwelshman on this, deeper blacks and more contrast would have helped, though I'm thinking a lot of it is just time of day and sun position.
