Agreed.
(ALL IMO BTW)
Very messy( effects are everywhere )
Complete lack of flow.
LQ and streched out
The focal is in the center of the signature = bad. (rule of thirds)
Lacks lighting (white spots arn't lighting, it looks like empty space)
Lacks depth aka flat.
Work on your composition
Overall it is a nice signature with seems to handle some of the basics quite well. You should practice more with lighting, coloring, and depth. Also be very carefully with resizing. Post moree workkk
