Impressive indeed! Does look quite realistic.

The only flaw I can see is that the water line on the boat doesn't quite seem right... I dunno, it seems like the line is coming up too far, or the water's too low on it, or something. Or the water line on the boat doesn't seem like it 'connects' to the water the boat's sailing on.

That's about it, though. Not bad besides that. :-)

Oh, and about what you mentioned about drawing graffiti? Graffiti art ain't half bad, really, if done right. Got any handy? I've been itchin' to import some good tags into Jet Grind Radio on my Dreamcast...
