Could you help me? ( I need some art criticism, so I can improve) Look at my latest art, and just give me some pointers. I just want to improve.

Your art looks really great! One thing that I would focus on improving is the texture of the lines. Sometimes they can get a bit to thick and sketchy. That can make a drawing look less professional than it really is. Otherwise your work is amazing. That was just a weird little critique, but I've had some trouble with the same thing. My work looked a lot better after I drafted a little more and worked a bit on how I use my tools. Sorry! Have a nice day.
