upper90- practice simps more before you bend your bars, add extensions and shit. everything you did is practically in the wrong place. go slowly with tweaking yo letters.
i wouldnt waste any time outlining them, i would practice on printerpaper or something cheap then throw it in your black book if you got something you like, but its up to you.
rib- yo mean the style of the R or the whole piece? i understand for the R though, shit looks stiff and awkward. ill try some out next time.
Rasm- that XEROx doesnt look to bad too me. I would just fix that R and the middle of the E makes it look like a sideways M. but the Z O and X is lookin good. and bar width on that isnt bad, it just looks like a quicky pencil sketch. good practice man
