Het begon allemaal met een idee...

The simpler you keep it the easier it will be to work with down the years

A bit of polish or some 'tweaks' as we say in the business.

Blue skies

Weak design, we also made somerhing equal ourself.
No relation with our core values

You are just bloody rude. I thought you had included those examples as something you wanted not just as something you wanted to w*nk off over!

In text is mentioned to creatie new logo. Those examples were to give you rough idea.
Please use our values (co-operation, free, local and party in your design)

It does Express FREE (reminiscent of free festivals of the 60s 70s), LOCALl (it is deliberately simple and friendly and not corporate) and PARTY (the logo is wearing a party garnish. That you don't get the subtlety is a concern. I suspect you want an illustration to represent these aspects more literally. If this is the case perhaps you should say this instead of wasting everyones time and being ignorant and rude about designers work. You may not know anything about branding but I will give you one tip. Designers are only as good as the brief. In most agencies a design and marketing team would discuss the brief before setting it, so don't feel too bad that you clearly don't know what you are doing but please learn some respect for those that do, and show some manners.
