Well since it's paid, I should be critical! Ok, so here's just all the very small things I'm going to pick about, since these are the things that in the end will need to be fixed anyways.
The space under the H is pointed and less rounded. Should be parallel or at least visually parallel with the top of the H.
A few rogue pixels here and there:
One at the right side of the H where the bend meets the vertical part of the H on the outside.
One at the tip of the first I in the black section.
One darker blue pixel in the lower left corner of the 30 Block where the curve meets the horizontal line.
Also the 30 Block's lower right corner is less fluid than the left side, the parts where the curve meets the horizontal and vertical lines are noticeable.
Most of these are less noticeable with the blue background but in that, the blue squares the letters sit on appear thinner and a little bit awkward. By awkward, I mean their thin appearance there, I like them there, just make those a pixel wider in the blue version.
Hope this helps!
