I don't know the ship, so I can't comment on the accuracy or not of the drawing, but the drawing itself needs some more work, as Eswube commented. I would also check the rigging, as it looks somewhat lacking. Sailing vessels tend to look a lot more complicated, all those lines and rigging.
I would also like to mention that your fonts and use of credits is not to the Shipbucket standards (look at the drawings at the above link to see what I mean). also see this
for style guide.
Thank you Kim for the crest
