Very good. Actually, there was one other thing... I'll get to that in a second.
First, thanks for being brave enough to post a pic... ANY pic ... here. =)
On the plus-side:
Two hands on the saw.
Proper helmet.
Tied in twice.
Safety glasses.
On the negative side:
No undercut. Yeah, we've all done it, but it can screw you.
Earplugs? Maybe... hard to see if they're they're or not.
In general:
Power lines! Those look pretty close... I hope you were paying attention to that. Or does it just look that close? Remember, it's not just where the branches of the tree you're in are headed than can kill you. It looks like the branches on the tree you're tied into are headed straight for that can (transformer). Your movement can bring branches closer to the lines.
What are you standing on?
