As for your accent, it sounds like your own accent, and more generally someone from The Netherlands.
If you wanted us to pin it onto a native accent I would say it is more 'American English' than 'British English' (RP specifically) as a lot of the words you say don't use diphthongs that RP would use. However, this is a very overgeneralised way to describe it.
Your speech is very intelligable, indeed more so than some native speakers I hear!
