Nice shots mate, I'm with the herd on this one - the second is a fave. For steadiness have you considered a monopod - some of the newer models fold up nice and small? Or how's about a Gorillapod?
Out of curiosity do you shoot through the viewfinder or via the LCD. I know I'm probably telling you how to suck eggs but the VF will steady the cam and give you a stop or two advantage.
Well that's my know-all rant done
Thanks for sharing mate....looking forward to more.
