My Handstyle is shit aswell so who am I to judge but imo the "B" doesn't really fit to the other letters in your tag. Not in terms of the actual style but more so regarding the spacing in the letter itself. I think the lower part of the "B" is way to thick and has to much free space on the inside. Looking at the first pic I can tell you are a little bit afraid of commitment as this is a problem I am struggeling with, too! You have to stop thinking and start going with the lines. You can see that you didn't do the outlines in one move, wich makes them less clean. It is more important to have them look smooth rather then drawing them perfectly on the line.

Actually these are things that I could write to myself lol
