Asking for honest feedback (usually from someone you're not close to) can be scary. If it's about your own work, it's nigh on impossible not to take it personally. Constructive criticism usually feels like it focuses more on the criticising side, rather than constructive, because being told how to improve still feels like you're being told you're not good enough to start with.
I used Peek Test, a service which shows your website to a stranger and records them using it and their feedback. Peek? More like Eeekkkk!
