Beginning with your avatar, I like the concept of going "3D" with the snake tongue coming out of the circle and I like that it is animated. I dislike that the white border of the snake tongue is cut off and the roughness of the circle. I'm not sure what software you used to make it, but in Photoshop, it is caused by the matte being set to white when it should be set to the background color of where it is going to be. In the case of Cracked.to, the matte color should be #222222.
Your profile cover integrates well with your avatar. Now that the snake head is bigger, a lot of the mistakes are coming to light. The black border of the back tooth is nearly gone. The black border along the top is faded away. The area where the tip of the tongue connects to the base of the tongue could be smoother. The text looks good, and while it looks good with the rest of your profile, I'm just not a fan of it (personal opinion).
With the photo in your signature, it looks good aside from the white border being cut off on the right.
I always confirm through PM. If you are dealing with me off-site and I do not PM you on the forum, you are dealing with an impersonator.
