Really nice job. Honestly I am not a fan of the bionacle/ hero factory pieces. I prefer more traditional pieces but I have seen some of your other builds in addition to this one and every single time you make it look really good.
Turning a dinosaur into a war machine is a very original idea! The cannons on its shoulder are nice, and his overall structure is great! Good luck in the contest... even if you already received your first vote :)
This was quite difficult to decide, because one entry shows better technique and refinement, and another more originality and charisma. I'll vote for you, because I have never seen something quite like this before.
