The sites look fairly professional, but you have to scroll down before you see any real content. That may be ok if you are a long established site with a lot of traffic, but not so good for newer sites.
The second site returns with ERROR
I like the design for Aphaground
Png-icons.com looks nice but it has too many adds. I don't think you should write the same things several times. I mean the information regarding broken links and etc. You've mentioned it at least twice at your homepage. I would add more samples of PNG Icons instead.
