Erm...no thanks. For me, experimenting is the best...

Realistic space scene! Good! It can be greatly enhanced with colours.

Try reading some tutorials. The skills you learn can help you to make your background.

Hmm...the links are broken right now, so I can't see anything.

Good work. It flows with the text,border and background.

Very very good. You might consider changing the colours of the sun rays to yellow and orange =).

If you are an expert in MS Paint, you can even create a piece of art even better than Photoshop! Don't feel left out, though...

You might also want to try googling it.

For me, its just experimenting until I get a good one.

Happy Valentine's Day. And oh,you might want to change the colour of the font.
