This might be a little hard to explain, but I think you should practice writing the word rather than individual letters therein to improve your flow. I rarely practice letters but write random words over and over instead. Over time you get a feel for how the letters "fit" together as you write. As is, it feels like you're writing the letters but not the word. Case in point, the S in bottom left has some style potential but doesn't match up at all with the rest of the letters. You're writing "TAIN" sharply, so adjust your S to match that sharpness or write them all in more rounded form.
OWINE: Drop the start at the bottom of the O since it makes it look like a P sometimes. If you're going for angular then make your O angular as well, otherwise, make the other letters round like your O. LONER: Clean af, legible, nice kerning, and good balance on the L and R shapes. I would just increase the width of the N a bit and fix that D in RBD since it's too angled and not the same size as the rest.
