Lovely work again!
I especially like the second avatar with all the text in it! You've managed to make such a small piece not look so overcrowded with all that writing which is brilliant and the border looks great too by the way!
The signature is also very cute and the font used for the text looks fabulous!
The black and white theme works really well and I like how the girls head is faded behind Riku's so that the focal point is more established.
The 'Please Oh Baby Don't Go' and the 'Secret Place' avatars are adorable too by the way! I love the text and the images you've used.
The simple one pixel border rounds them off nicely.
Well done and keep up the good work!
