Your templates are nice and have good use of color. But why would you have the stock photo promo pics as your product images instead of the mockups? I can't decide if it comes off as gimmicky, as in you're trying to be trendy with no justification beyond that, or deceitful, as in you're hiding the product/trying to make it look better than it is. Neither could be the case but that's how I interpret it. Either way, that's not good. You're clearly a good designer; own it!
Also, your Twitter link in the footer is broken.
