I think you need to work more on your letter structure and consistency across your letters, looks like your S belongs to a different piece, and your E is not as heavy as the rest, for example.
Looks like you design each letter individually, whereas I'd like to see more integration through out with the shapes and structure. There isn't an overall flow to this piece, its just "letter" "letter" "letter" "letter", I think if you flex harder, and wild-out more and take more risky and daring lines, while at the same time dialing it back a bit in terms of complexity (both in terms of letter shape, and chunks and bits and arrows etc), you'll find great success.
Make your loops and kicks bigger, more crazy, use visual weight and negative space to your advantage, theres a lot of awkward negative space in this piece between your letters.
Technically you can draw very well, your perspective 3D is on point, a very difficult style of 3D to do well, i might add.
Keep it up though!
