Following a previous post I made about my watering hose timer reverse enginering and with the suggestions about using a step-up IC designed to boost the voltage I came up with the following design, since I decided not to use the original design and make a new implementation I have created a new post.
My question here is, since this is my first attempt, I would like to have some advice to check whether is anything wrong with this design? Are there any obvious flaws with it?.

- Is a good idea to power the HBRIDGE from the booster circuit ?
- The mosfet controlling the booster circuit, is a good choice?
- I know the led part seems wired, I haven't used any multiplexing technique nor any IC but I want to reduce the number of components of the design to improve battery life and since I will be using a MCU with lots of spare pins and the leds will be placed all on the top layer of the PCB and the mcu on the bottom it will make it easier for me to route it.
