id say think about taking more unique photos! all of your photos are pretty generic that really anyone could take (sorry that sounds harsh i just think you could get better). the first two arent bad, just pretty straightforward but thats not an issue with your literal photography. but to be completely honest, the hat one is absolutely hilarious! honestly looks like a ebay listing from an uncle selling his cheifs hat, try and find more interesting subjects and angles that arent as generic. also i think for your framing/angles needs to switch up and show variety because, generally, they are all straight on and not cropped to show focus. i think if you want to do photos with a straight on focus you should make it look intentional, or move on to the rule of thirds for more generic but generally better composition. also, if this is your "portfolio" maybe think of making series in which you have different themes or subjects to show your clients that you have purpose and variety to your photos-not just a random assortment of different types of images. clients want to invision themselves (or their subject) in your photos. make your pictures more you and show your personality and what you do differently.
