Oh thank you!
I've been drawing them for years, since I could hold a pencil. I stopped drawing for nearly 6 years though and have recently gotten back into it. It feels like I'm learning all over again.
My top tips would be:
•practice practice practice!
--whenever you get the chance sit down and sketch
•Study. Find photos and tutorials, muscle and bone diagrams also work great. Study and practice them
•Trace. I know this is a controversial subject among artists but I'm pro traceing. As long as you don't claim that art and don't post it I think it can be an amazing tool for learning shape and movement. It helps train your hand.
• Find reference images (there are several good stock holders on deviantart) for when you want to draw free hand. It's a great guide. It can be frustrating but you'll learn

• Keep it fun. No one wants to do a job that bores them. I've found that doing art challenges can be a great way to keep you inspired
Bonus tip- asking for a red line is a good way to have someone basically check or grade your anatomy. Remember that other people have different styles than you and you dont have to give up your natural style.
Hopefully these are comprehensible. I just woke up about 5 minutes ago. Feel free to message me if you ever need more tips or anything like that.
