You are coming along nicely indeed.
Am looking forward to your completed drawing (which is almost done, now).
Apart from the obvious about the credits (fonts should be anti-aliased), I think you should also have a second look at the stern. The propellers, although look better now they seem to jut out from their "stern tubes(?)" awkwardly (for want of a better description).
Thank you Kim for the crest
