I think that all of the tags are good! >o<
I really like the style used in the autobots tag.
It's just too orange.
you use effects really well.
If it's alright with you, can you make a tutorial to maybe the Transformer sig? I would really like to see how you make your tags and your style.
nice tags, overall.
Some could be a little worked on to be better, such as the one on top of Transformers tag. It is too empty..
Good job, and keep it up.
