yes. there are detail differences. as far as I can see, you have done the following:
you have rescaled andrew arthur's drawing
you have kept the outlines, and copied parts of andrew arthur's drawing. (look at the scuttles, they are copied directly, they are even still the originall size of andrew's drawing.

You leave so-called "pixel trash", you correct most of thing after resizing but you forgot to correct lifeboats. We are not blind Barham, we sit in this business for too long to recognise plagiarism.
You work on paint, not paper.

Barham,if in your own words you" have hardly got a steady hand" how do you explain drawing such a gem in the first place ? You cannot just take someone else's drawing,re-size it,change a few minor details and claim it as your own work.
