1: Well this isn't an error with the model, but you should probably post it in the Model Section instead of Maps.
2: The Stomach is see-through.
3: During its attack animation. It looks like it separates into pieces or segments.
4: Only has one attack animation
5: Its burrow size is disproportional to the worm. "In game at least, Can be change if people use"
6: During its stand animation the teeth don't seem to be part of the mouth. "They move separately"
7:*Map Specific* In my opinion you should make smaller worm(s) because the worm looks really wierd when its tail slides at an angle when it turns.
8: Horns and the head looks wrapped a lil funny.
Overall descent for a first attempt, and very unique idea. Just a little more effort could have been spent on some of the little things.
