A slight change in fonts and choosing a more saturated color (it looks too whitish now) would make miracles for you Anyway, my overall impression is - "Yes, it is a decent logo which could be enhanced a bit"
looks great to me though personally i think i would use a different font. Helvetica, Univers or some other sans serif type font would probably look better.
Not sure about it myself, what's the context for this logo? Looking at your site, seems to be linked to chemicals/science. My opinion is that the font is too weak, the grey colour doesn't stand out too well for the small text and the magifying glass placement doesn't make sense. Why is it focused on half the O and T? From a distance looks like "Spat". My suggestion is to make the magifying glass the O or place it on the end, or contain the whole of SPOT into the glass. Sharpen the font and colour, dark green would be cool. Perhaps also a better tagline will better describe what your site does?
A nice logo dude. You might consider change the font and move your slogan next to the word "alpha". Additional, maybe change the font color from grey to green/blue can have a better look.
I like the logo but i think you should make the color of "Alpha" a little darker. Also change the "green" color of magnifying glass to look different than "Alpha" Overall it's a nice work!
I would change the font, most definitely, and probably add a subtle shadow under the magnifying glass. Also maybe give the magnifying glass "handle" some sort of shine to it so it has that nice rounded 3D effect.
Its looking nice but adding something around the R of the reference will improve things. Because it is a bit longish and looks bare on the left side.
You can make the letter O like a spot and then place the magnifying glass on top of the spot so that it looks bigger.
