Welds look good but either turn the heat up a little or the feed down maybe 0.3-0.4 between marks on the dial.
All the welds you should be pushing the heat so that you prewarm the material in front of the arc pool then fill with wire which gives better penetration, if you pull the torch/arc over the cold material you get a cold weld and it lays on the top which looking again is what you might have done.
The problem with doing short welds to practise with is by the time you've got your eye in you have to stop. MIG welding 1.6mm material is a balance between penetration and not blowing through, I run my MIG at 180 amps with 0.8 wire with the speed around 4.5-5.0 Yes according to the books it's too hot but it means the first arc is hot to get the root in. If you have tube spare put two lengths side by side and do a long run up the middle,when you can get a smooth bead that's not too high then try again on the short runs.
