Mike, straight up- outside of Nashville a portfolio can only support 1-2 images of a girl with a guitar... I'm not a fan of any of the guitar shots you have up but then I'm not a fan in general so that decision is all on you.
Assault rifles are a bad choice at the moment.. just saying. Not really into the model either. again YMMV
Your portfolio seems to have quite a few repetitive images. It only takes one shot to show you have a given ' club in your bag', two if you want to prove the first wasn't just a fluke but then you really need two different models. May want to edit some of that down.
How do I say this???? You overwhelming failure might be that you're too damn nice... sending you a PM on that one
Consider hiring a make-up artist and brush up on your Photoshop skills.
Let me point out a few that I think were done well:
These demonstrate that you get it and can do it. Your portfolio should be filled with this type of image.
Absolutely agree, those 3 images are your best
