Second time MIG welding. How did I do?

In pic two the only weld that is mine is the leftmost one and same for the first picture. This is my second time touching a mig welding machine and would like to know how I can improve. Both welds are overlaps. I've done a bit of stick before in my welding class and wasn't very good at it so don't hold back, I want to improve! Also if anybody has any recommendations for an at home mig welding setup please let me know.
