I've been interested in modeling for quite some time now and have been looking to get more serious with it. I would love some feedback as to how my port is, which ones look the best, which ones need to go and what is missing. Thanks so much!

You have 2 images covering the same "wardrobe" for two separate "wardrobes".  Delete one from each.  This will leave you with 4 images.

Then find an experienced photographer to work with and upgrade your portfolio.

Best wishes!

But just one worthless opinion.

has a "kitchen sink" in your pocket - a phone probably thats printing through the clothing.

Men do this often, must take stuff out of pockets, shooter should have caught it. Other than that you look good, take a couple of real polaroids and post them to get more bookings.

The two last photos look like they were shot with a webcam. They gotta go bro

Keep 2,3,4 use 3 as your avatar, take more images. A few concepts & maybe a couple shoot .. Your hoodie images are my favorite .. cool abs .. Implied black & white or color if you're comfortable with it.
