Help with Clap on light switch, ATTiny85

This is my first post on this forum, and im also really new to arduinos and have very little electrical experience, so please explain thoroughly, thanks.

I looked at some designs for clap on clap off light switches, but i didn't want to use a breadboard, to save space, so i made my own design, which i will attach below, I just had a few questions.

First off, does it look good? (not estethically of course lol it looks like ***, but I mean does it look like it will work)

also, the relay on the right side of the circuit, I don't know really how relays work, so if somebody could explain what to do when i get there in the design, because right now i just drew it in, I don't know what to do. I also read that relay's were very taxing on the battery, so is there another option?

Thanks a lot

I did exactly what @shabaz suggests for my project and found a circuit similar to what I wanted http://www.element14.com/community/community/design-challenges/enchanted-objects/blog/2015/06/04/enchanted-objects-design-challenge--knock-knock you might find that this kind of circuit works as a detector for a clap circuit but you would need to adjust the resistors for your example. You could add a microcontroller or even a simple toggle latch. Small circuits can be made up without a breadboard just wiring between the components but I typically would use a strip board for this kind of thing.
Definitely worth researching how relays work so that you understand why they might use up your battery.
