Nothing fancy at all, just a bit of a practise sketch! I tried to create this really quickly so I didn't stop and think too much about what I was doing. This is something I really struggle with because I work digitally - everything is usually so precise and I spend a lot of time looking at little details, trying to make sure they are perfect. It's nice to explore other ways of working in Photoshop from time to time!
I must just say, if you are looking to start illustrating etc, you really don't have to shell out on PS, there are plenty of other free applications you can try. Krita and GIMP spring to mind and include many of the same features as PS. Give them a try!
