Cool paintjob....Good effort!
Always great to see people having some fun and being a bit more creative with a DIY rattlecan project like this. Just jumping in and figuring it out as you go is the best way to learn what works and what doesnt in my opinion. All you need is a rough idea of what you want and open mind and you'll end up with something interesting, even if it's not exactly what you were aiming for.
As long as you dont go into it expecting to achieve a super high quality finish, and just want to have a bit of fun and make your bike a bit more unique, you cant really go wrong. People often end up wasting a huge amount of time and effort trying to get a perfect finish, which just isnt possible with rattle cans!
Dont get to concearned about the paint getting chipped and scratched though - paint needs to be protected by a decent 2k clear coat to have decent durability.... Which just isnt really possible with rattle cans (You can get 2K clear in a can, but its pretty shit) - So not being to fussed about the finish getting a bit scuffed up over time makes life a lot more enjoyable!
