Relevant experience etc

After graduating from University with a First in Law I decided to take a year out to decide which route I wanted to follow. I had initially considered following the solicitor route however after work experience in a corporate/commercial firm and some interviews with magic circle firms I realised I really had more of an interest in a career as a barrister- particularly in the areas of family and criminal law. As a consequence of making this decision slightly later on in the process than some of my peers I fear I may be at a disadvantage. I have already completed a mini pupillage with a provincial chambers (criminal) and obtained work experience shadowing a cps practitioner. I have secured future mini pupillages with two of the top london sets (family and public sector etc) as well as work experience in a niche family solicitors firm (just to gain more insight into the client in this area of law). I was advised that this experience would be adequate, however after reading advice given on your site which prescribes undertaking several mini p's I am concerned I have not done enough. Unfortunately as I do not live in London and have to work full time it is difficult to do much more. I have experience in debating, making it to the regional finals in a European Youth Parliament competition and have experience as a representative in several roles during my school and university career. I also won an academic award for my degree results. This year I am volunteering as a youth offender panel member as I have a keen interest in youth justice. I plan to take the BVC this coming Autumn in a London bases provider. I am just wondering if you could advise on any glaringly obvious gaps in my experience which might limit my potential for success or recommend any extra pursuits which you might deem helpful?
