First, your work is not atrocious. In fact, your hard surface modeling work is pretty damn good. The character could use some more polishing up, but it’s still good effort. Stop underselling yourself and have a little confidence in your abilities. You’re only getting better each time you boot up Blender.
As for and CG stuff in the UK, I have no idea. If you want to get your work in front of professionals, try catching one of the critique streams here in the future if you haven’t already. Kent has been very helpful to my work and others’ work as well. Hopefully someone else can chime in and help you with CG events in the UK. Good luck.
