I just revamped my portfolio and added some of my new work. Any opinions both good or bad will be greatly appreciated.

Thanks!

Your latest 3 photos are headed in the right direction. If you can get more of that level of quality, you should delete almost everything else in your port, as the rest of it is pretty bad.

This is now your best photo:

The lighting is reasonably good, she has good make-up and wardrobe, and is a decently attractive model.

Watch out for where you crop things though. Both on that photo, and the others, you're cropping off hands.

Additionally, due to the dramatic lighting you're using here:

her eyes are dark, which is why I'm not wild about that photo, but otherwise it's still much better than your other work.

This feels forced, as though you had been directing her every head movement, and then she smiled and you snapped:

You were probably going for 'creative' with the hair over the eye, but that element doesn't work for me either.

This is just very plain:

When doing artistic nudes and bodyscapes, it works well to position a large light source close to the model, behind them, in such a way that the light can skim across their body, like this:

For your older work, if you don't understand why it's bad, you are welcome to post URLs to specific photos you'd like me to critique (pick up to 4). It would take too long to do them all.

Again, you're headed in the right direction... definitely a significant improvement in quality in your most recent 3 photos. Keep learning and growing.

I appreciate you taking the time to provide feedback. Cheers
