Personally, I think I have to provide some constructive criticisms rather than just saying "nice", so here we go:
- I have to zoom out really far to see the images (for example on my normal zoom level, I can only see squirtle's mouth), you need to compromise for smaller, low resolution screens which many people with laptops still have to deal with =P
- Your username on the left is really bright and is kinda distracting, it would be nice to tone it down to a less bright shade.
- I can see that you tried to line up your background with the links you have, but it's not really lined up well. The text in the background can be moved up a bit so that it lines up. Also it has the same problem with squirtle and the other images when it comes to the screen width.
But your background is really nice though! I like really like the lighting and the white sparks. Also you used up all the space you can =P even the 22 pixel space for your link =D
it is definitely very aesthetically pleasing channel
