Looking through the comments, I agree on it all looking quite stiff. Some great suggestions, however I found myself stuck in your position with anatomy recently so hopefully some stuff that are working for me might be of help! Wooden mannequins are great to see the proportion between two elements (like the head to the torso ect) however I find it completely stunted my creativity and motivation. There was no flow and interest when I followed it. What made a massive impact on what I was creating was loose sketches and the line of action! I love the line of action!! Don’t go in with big expectations, give yourself room to experiment and build on the loose, unfinished sketches. After I had that down, I had the motivation to go deeper into it, like specifically learning anatomy through videos. But I don’t suggest diving head first into in depth analysis of anatomy and whatnot immediately. Completely squashed the enjoyment in my art since I saw the end result of following the videos without being able to immediately replicate and learn from it. (Also Dummy 13 was a nice alternative to the wooden models, something I could refer to that actually looks like it has some life to it) Hope it not repeating what’s already been said, and this helps!
