I would like to criticize the new logo a bit. I like it on the whole, but I think a few minor tweaks could really make it shine. It looks fine at smaller resolutions, but blown up large, a few flaws appear.
I will work my way from left to right through the letters:
*Space between "i" and "t" is a bit too tight
*Space between "t" and "s" looks a bit clumsy. In general, I have a problem with the "s" glyph as it is asymmetrically longer on the bottom left. On the right side of the "s", the top line and bottom curve line up perfectly. On the left side, the bottom line protrudes further to the left than the top curve. I do not like this asymmetry, it makes it look like it is about to fall over. I think that it could be negated in a way that looks nice with the hook of the "t" lining up nicely with the end of the "s" curve.
*Too much space between the "s" and the "h". Compare it with the space between the "h" and the "a", it's like twice the distance.
*On the other hand, the "h" and "a" are too close together, separate them by a little bit.
*The top tail on the "a" should be extended slightly and curved a little more to make complement the curve of the "h" next to it.
*The space between the "a" and the "r" should be closed a bit.
*The top tail of the "r" should get the same elongation treatment as the "a" to have it come closer and give a nice complement to the curve of the "e".
*The final "s" should be corrected like the first one, and moved slightly towards the "e".
I have made all of these changes using the blunt tool of Photoshop. (My Illustrator version was too old to work with the EPS file.) I humbly submit the revisions below (with the original on the bottom, my changes on top). When seen as a whole, it really does not look much different. But when you look at the individual letters, it looks much more harmonious IMO. (Although it really needs more work, there is a little glitch in the "r". And I did not fix the "s" completely, as doing so made it look top-heavy, but I did shorten the length of the bottom curve noticeably.)
