Looking at your drawings its amazing how you drew those within 2 weeks. The body proportion is amazing same goes with the posing and the way its in a style your own. I say with the amount of practice that you do its really pulling off. I say keep doing what you are currently doing and if you have some extra money to buy some books on the human body. As an extra boost to build up the structure to give the body a bit more detail, when you finalize your drawings,but in general they look really great.
Your drawings of the cats have improves so muched from the first picture to the lastest picture. Its looking good so far. I say you take a picture of the cat you're going to draw and use the picture as refence to then draw a quick skeleton on where the head,body and facial porportions go. Other than that take some time to do a full class and challange yourself on drawing other animals.
Your work is really good for a beginner. I like to use a skeletal fuction to help support where the each aspect of the body goes and the head. Like circles and lines to map it out and then later filling it is. Other than that your work is pretty good. Keep it up!
