First of all, that crosshair looks nice (something between okay and good). But I think it is a bit too transparent.
This crosshair, lagicon and other customizable stuff gets a bit annoying. Srsly, if I want another lag icon, I make one. If I want to have a different crosshair, I make one. But I don't post it here. Why? Its easy to do. Nearly everyone can change the blockland logo, make a new crosshair or whatever. If it looks good or not is another question...
