Lost Simba

I done this in photoshop with my tablet it is one of my first drawings with it and i'm still trying to get used to looking at the screen while drawing down on the tablet so at the moment it looks a little shaky but hopefully i will improve. I'm happy with the way it turned out but if you find anything wrong exept the shakyness can you please tell me so i know what to improve on.

PS: background is not mine i found it on google a while ago.
