Initial concept drawings

The theme of my idea is anti signs, i thought about doing toilet signs with a twist, usually mens toilets are labelled men and the womens toilets are labelled women, but i had an idea to do the normal men and women toilet signs with an anti sign over it.   For example the mens toilet having a sign of a women crossed out and having men written above the sign, with a small lettering beneath saying no women allowed,  I really like this idea as it is simple yet affective and is also original and hasnt been done before.

 Here is a example of my initial designs after trialing the typical thickness of an anti sign and also the typical men and women symbols, i decided to take on a more symplistic feel,  re designing the traditional symbols of toilet signs, i also prefer the thin lines rather than the thick lines, i feel it looks slick and more sophisticated.

I also looked into incourporating this idea throughout the school and switching signs around, for example, having a keyboard sign crossed out and instead of it being a compter suite it being something completely different.  But im not sure if this would work well througout the whole building as people would get confused on where to go, and visiters especially would get lost.

  Here are further trials on my idea of anti signs, the sign on the left i created in photoshop, although as its digitally done , and it looks more professional than the other trials, i prefer how the hand drawn trials look.   I also found photoshop very challenging to use, and im not too pleased with how this initial tral turned out.
