I like how you're practising on your opening, good job man. I'm kind of confused on the "closest washroom" opener though. When people are outside in the day they are always moving unlike at night when they're mostly in a club standing still talking to folk. A moving target in the day is harder to open than a stagnent target at night. Keep opening indirectly, use the "closest washroom opener" but don't move onto a direct statement like "I actually dont need to go, that was just an excuse to get to talk to you... you're beautiful."
Notice how on the opening you are immediately giving her value by telling her she's beautiful, by saying that you are implying she has higher value and on the same note, by chance, yours will be lower in her eyes. The aim of the game is to keep higher value. NEVER COMPLIMENT HER BEAUTY, if anything compliment something she does or something she wears.
Now let me explain how to escalate, I go by mystery's A1, A2, A3 method. A1 - opening, using an indirect opener (under the radar) to initiate a conversation with a target. A2 - Female to Male interest, notice how we make the target attracted to us before we show interest in her. We do this by throwing a neg, a back handed compliment such as "I like those nails are they real? [no] oh.. well they're still nice". A HB 7 or 8 will need 2 negs and she will throw indicators of interest once you have a few IOIs you move onto A3. This is Male to Female interest, ask her what she does for a living, compliment it if it is complimentable. Remember, in her eyes she is wanting to win you over because you have the higher value. Throw in some compliance tests or kino tests to escalate and then for a K-close.. my favourite is to stop talking and if she says "soo..." (which is an IOI) then say "do you want to kiss me?" if she says yes your in, if she says no just say "i didnt say you could, you just look like you have something on your mind" if she says maybe or something similar say "ok well, lets see..".
If you don't K-close then get the number by saying something like "I just realised I had to meet my friends 5 minutes ago, damn you for keeping my time (say playfully).. pretend your about to walk away and then say "actually whats the best way of keeping intouch" doesn't matter what she gives you as long as its something. If she doesn't then say "fair enough, it was nice to meet you *insert name*"
If you want to learn more about this method then look up "Mystery Method" on youtube or google. I also suggest Adam Lyon.
