You want a critique? Okay, so this is my first critique, and I'm going to have this ([link]) as a reference so i don't give you false information. This critique is mostly going to be anatomy tips.
Head: Personally, I think the ears are too big, and should be lower on the head. It's cheeks could use a little fluffing out, even if it is short-haired. I get that the eyes are your own style and i love them! They help others tell that the art is yours!
Front legs: Okay so, not to sound harsh, but they look like little logs on the cat. Try to find out where the joints are and make them show. Also, the paws kinda look like it's doing ballet. I would suggest trying to define the toes a little more.
Back leg: Your back legs are done very well! The only thing i ask of you in this category is to try and make the foot under the legs.
Tail: Your tail is done extraordinarily! I only have one tip for you here; Try and be sure whether your cat is a long-hair or a short-hair because this will help you decide how fluffy/rounded your tail will be.
Overall I really like your style and am sure that you can improve your style to have a little more anatomy and have it still be your beautiful style it is! (Sorry if this critique sounded a little harsh. I would really like you to look at some pictures of cats/your own cats to help with your anatomy)
