First of, I feel that you most definitely need to show more interaction within the community, this could be in many forms, but it doesn't seem that you show your face and interact with the rest of the community, which is vital for becoming a lead team member. Make sure that you most more on the forums and join the TS more and talk to people. I also feel like you could do more F1's within a week, try and aim for 60+ when going for a promotion. Apart from those things you seem to be a very friendly guy, who does a good job, your application is good and seems to have enough relevant detail. Keep up the good work, work on what I have said and you could become a good lead team member!
Good luck buddy!
