You're welcome :D Your advice isn't rubbish, actually it's quite helpful because as I use Photoshop I'm overwhelmed by how many brushes it has by default and don't know where to start. And I've always wanted to use Gimp but have not used yet because it seems so different from photoshop it scares me /o\

So thanks for your advice! I'm going to try my hand at painting with Gimp now :D
