Please read the GUI rules. As stated in 1.1 just putting the website where you got the image is not enough. Please either add the actual author or if you don't know please add "Unknown original author".
I have fixed your recent submissions due the withhold tool being broken, but in future please do this yourself.
You know what I'm really sorry, but don't think I can have more people in our studio and I think you are a good mapper... but not the best... So I have to say... no. Maybe I'll hook up with you in some months and see how your mapping goes then ^^
and if your skills have progressed I will definitely let you into the studio ^^
