Hello! It is nice to see that you're back to drawing. 
As for critique, I don't think there is need for that at the moment. However, I can guide you as to what you're lacking at the moment!
Ok so, the things that I like about your srketches so far are that they are organic, and you're not afraid of using bold lines. There are also few chicken scratching lines, which is always a plus. I think your technique is a bit too rough though--I understand that these are sketches, however, you should take your time while doing practice!
Figure drawings are very good to learn, but I also think you need to delve a bit into anatomy to get an understanding of how things are put together. That way, you can create the shapes accurately, and can correct things that seem off. Either way, as a last comment, I think you need more (?) sketches per day to effectively progress. Any amount is good though!
Great work so far!
