@helenril Makes me happy to know you appreciate the effort I put into these.
Here are all the tools I use.

The best advice I can give you is this. "It takes 10,000 miles of pencil lines to become a master"(or as Macklemore says in the song 10,000 hours ;D) the philosophy can be applied to any skill. Just means keep at it. Everyone will do things a little differently.
How ever if you have something specific you would like help with I would greatly appreciate you letting me know what that was and I would gladly make a post trying to address the matter. Thanks for reading through, cheers!
