The first thing that caught my eye was the fact that the top texts 'Mouthful' matches size with the bottom image. I think that looks very nice and well put together. The colors you used are simple and pleasing but the different shades of blue add a little spice to the signature itself; I really like that. It's well-aligned in the center, with an equal amount of space on both sides, and I find that really pretty. The gifs on the sides match up with the images and quotes really well. (I also like how instead of using a dark blue and light blue on the quotes, you used a black and light blue)
I don't mind how long it is, and just a heads-up: I'm a little sensitive to criticism but I appreciate anything and everything, thank you!
