1. on the first one, you FUCKED UP the structure of the R, like big time. don't make the upper left part of the R so wide next time. everything else is IIGHT. i personally hate that style so it'd be hard for me to say shit without sounding negative. oh yeah, and clean up your lines, they got sloppy when you were doing the outline.
2. on the second pic that R gets shitty towards the ending bar y'know, the \ part of it. it's like you put a pocket of fat in the R at the right middle part of the R you tucked the E behind the R. move the opening on the bottom of the E to the right. The S on this should be like the first pic's S. the I on this one looks awkward, make it like the first I. the T is good.
3. the hole of the R was placed slightly to the right. align it with the middle part of the R. you left too much dead space on the IST on this one.
4. show us the toss on top left part of this pic, the R looks really good on that one.
