You can if you hold down ctrl and scroll.

 If you don't belive that we can zoom it properly - just upload picture containing 2 versions: native and zoomed. There is no possiblity to zoom out.

i like colors, but not understand what it is - to be onest

Not with Firefox ;)

 Yeah, I'm here, although I'm still very much of a beginner. 

Also, the zoom button makes it all blurry. :L

Hey Leo, I didn't know you were on PJ! Nice to see ya.

As for the piece, I like it. It's better to leave your stuff as normal size since there is a zoom built into the site.
