Solder joint

[Knightstick]

Hello, I'm wondering if these large solder joints are okay. I had real trouble getting them all to fit. I heated everything very thoroughly and pushed quite a bit of solder given it is 3 wires. I heated from one side and fed solder from the other. I hope this is adequate. I'm I'm talking about 36.

I would use more heat and more time.  Hopefully the solder you're using has lead in it as well.
