Hi, in my opinion, it's very hard to tell from the pictures on whether or not you have good penetration without slicing it and acid etching the weld, and or other destructive tests, but visually I have seen much, much, worse as a first attempt.

In the first pic, top weld isn't great and the bottom weld is better, same as your last pic, although I can't tell if it is a piece of thick angle steel that you have put a bead into the corner, if it is then up the wire feed and the voltage, as it looks like the bead might be sitting on top of the bend in the angle, although it does look like the edges have wetted in well in a couple of spots, so had to say just by looking at pics.

Your gas flow is too high, 8-10 lt/min should suffice as you are wasting gas otherwise. I personally would go up in the volts a bit and with a bit more speed/wobble hand control you will be on your way, overall not too bad.

Cheers
