Some of the text is
a bit cramped in earlier balloons, which would make re-lettering as larger text difficult... but even rearranging the lines slightly so that they're level would help quite a bit (at least it seems
a little lopsided in, for example, the fifth panel here
). Of course, some of the small and cramped lettering is, I believe, (please
correct me if I'm wrong) supposed
to be small and difficult to read, because it was spoken in a rush
There's always something to be said for that extra level of dedication (which seems rare in online works). Inking would definitely help, and (if publishers or prospective readers are picky) there are also programs to turn one's own lettering into a font... worry-free consistency while still being original. At first I thought you might have used something similar for the fragments of the letters in the first comic, but on closer inspection I'm not so sure... I have no experience in detecting these things, but the lettering is beautifully consistent and even.
Just my two cents... or something.
