Yellow Jack is a mech that lives in the forest with his creator Mushroom Cap. He helps Shroom out with any thing. He also has a conflict With Camy. Jack was first created for an army project but escaped the army because they wanted to change his color and insert a programed computer piolet. He is a mech that was inspered by a bee but the difrence is that he does not has any wings.
The way each piece was used here is remarkable, and the color scheme looks nice as well. From the side profile however, the width of the legs looks a bit disproportional to the rest of the mech. I'll award this a 4 - great effort. Interesting minifig you have there in the first picture by the way.
