Work on the nose and I think you're going somewhere with it.
Something's always bothered me about your drawings. You're getting much better, especially in the midsection and back. But the nose always looks off - kinda squished. Kinda like you rushed it. Take more time on the nose, and look at how others do their nose. Ask for some tips. You're improving, but the nose area still needs some work.
None the less, I like where you're going w/ that design. Rear reminds me a bit of Ferrarri.
