I'm really glad that it works, and please don't take this the wrong way... but the solder joints look awful.
The only reason I'm saying this is because I suspect that after repeated use, they might fail and you will have to redo them. Maybe redo them now?
May I ask what your soldering technique is? Did you by any chance try to apply the solder to the iron and then struggle to apply that to the pins? This is a common misconception among beginners, hence me asking - you're supposed to heat the pins with the iron and then apply solder to the heated pins, where it will flow into place. Also, applying flux beforehand will help with that.
