You should use another font, that one is not that readable from my point of view.
Yes, you should change the font for the fields and maybe work on the drop shadow for the text on the button. Also make the text on the button bigger. And maybe try different colours, imo the two you have used don’t match (colours for button and field outline and text on hover).
the button looks like twitter bootstrap btn. But looks clean
Thanks for the feedback guys. I’ll make sure to take a look at it. If anyone else has some feedback I would love to hear it. Thanks,
For what it’s worth I feel the font style looks fine just needs a little more contrast overall..
One more thing.. The green font color, and the button background color does not match.. Please try some other color as the background of you button.
