The lettering looks first rate. Very clean and uniform sizes, which is important; the letters should look like they belong together.
There are a few standout letters, mainly the O and U. The inside center shading of those letters is very well done and sets the letters apart. Its hard to do. Plus the shading on the leaves of the O makes a fine contrast on the outlined parts of the O. And I really like the little flower at the bottom.
But you also have a couple of letters that don't look right. The A is the biggest problem. It leans to the left, has a muddle of leaves instead of a cross bar and the top of the letter usually looks better if you have something coming from the normal top point instead of having a cap on top. And the B should have a horizontal bar from where the two right handed meet at their point to at least the single center line. Plus the top right half is over too far to the right in relation to the lower right hand side.
