so you are crossing the street with a green walk signal instead of the green light?

Looks like you're travelling from right to left in the pic correct?
And the traffic turning left is moving from bottom left to top left in your drawing correct?

Well, I'd go straight through the light on a gree signal only, that way there is no left turning traffic coming alongside you. I'd either stay with traffic if its the absolute best adn safe route, or filter up the far right side of the road. You say there is no space? Whats the shoulder? Grass? Gravel? Dirt? Guardrail? Cliff?

If you can filter up the side of stopped traffic its relatively safe IMO unless its a popular drop off (door-zone).
Ride like a car or a motorcycle, seems like traffic's slow and jammed in the area so should be relatively lower risk.
