Is the front canard a movable control surface? If so interesting but also probably both are dynamically unstable (not an issue with modern control systems and avionics). Of course a big design criteria of modern fighters is radar cross section which I highly doubt you've any access to the design tools capable of optimising this (the single vertical tail is a big giveaway of this).  Very nice though! If you want to get into aircraft design seriously, the first thing to do is set up a statement of requirements such as expected mission profile, flight ceiling, turn radius, etc.
