My current publications have been from model submissions, I haven't actually aimed to submit anything myself ... yet. That will hopefully change for 2015 and will be more active in submitting work for online and print publications. I've got 'semi' experience of some 20 years photography but it's only been the last 3 years that I've been doing studio and model photography solo and really seen my work evolve. I still feel that I'm way off my potential but as it's a hobby the main limiting factor is the amount of time available to grow and learn.
I haven't submitted anything to any big competitions but I've won numerous daily competitions and have featured images on many sites. One of my recent goals was to win a photo of the day in each of the three categories on ModelMayhem; Picture of the day, Picture of the day 18+ Female and Picture of the day 18+ Male which I achieved :) I'll often set myself little goals so that I feel my experience is growing in time.
