I feel that it looks too much like 'ND' vs 'HD'. On a quick glance - one may think that it looks like 'NA'.
The font is a bit boring - it could be that the kerning is giving it a tight claustrophobic effect - maybe space it out more.
All-in-all it looks like a step backwards from your current logo. The one on your site is far better and I think you should work on that a bit more.
