Drawing Characters For Practice

One of my goals for 2020 is to get back into drawing regularly, something I have not done for years; but I've been sat with my notebook and a pencil for the past half hour and am having trouble coming up with ideas. I see so much cool art on here, and so many people have such creative ideas with their characters, I was wondering if anyone could describe theirs for me to draw? Feel free to include any details you want, and I'll pm you the drawing if it doesn't turn out too awful :P

Edit: Thanks everyone! I'll try and do them in order over the next few days, I really appreciate this
