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.

Just a bit of useful criticism here.

The themes look all the same with only a slight variation on color and font use. Also it'd be nice to see them used in an example. Ie: map app, messaging app, photo, etc.

Great job though I think this space needs something like this.

Looks nice, but the website looks like you're fitting a left shoe on your right foot. Looks premade and needlessly crowded. Also the 'z' at the end of your name screams 2002. Otherwise, nice products.

Oh, man. This is just AWESOME. Great idea and pretty good execution out of the gate. Good luck!

Other than the font in "Jazz Age", you've got something pretty useful here.
