Hmmm...okay, well, first of all, you forgot the frill. Big thing, almost more important than an impaled victim on one claw. And secondly, its mouth is too large. The "chompers" would make him get off balance and fall over. And lastly, as somebody said already, the legs are far too thick. The feet aren't even claws. But it looks cool nonetheless--works pretty well as something besides an acklay. Maybe a giant, mutated mantis?
