Pack your bags and head for Nepal Ray.... not that your images are not good... it just seems way more fun to travel than to try and squeeze diminishing disposable income from others... I suppose you just have to work out what gives you the most thrills!
That's probably good advice. Selling prints becomes a business, and running a business is not as much fun as trekking in Nepal.
But heading for Nepal right now would not be advisable, unless you are fond of leeches. They're in the thick of the monsoon in Nepal right now. October, November, December are the best months, but March, April, May can also be okay. January and February are far too cold.
I'm contemplating doing the Annapurna Circuit this year in October. It's roughly a 21 day trek, or shorter if you're fit. However, I'm a bit hesitant about the Thorong La pass. That's 5400 metres and causes some trekkers a lot of trouble with altitude sickness. Reading accounts on the internet, it seems that some folks take as much as 13 hours to get from the last lodge, Thorong Pedi, and over the pass, Thorong La, to Muktinath, which involves a 1,000 metres ascent followed by a 1600 metres descent.
I'm not keen on boasting about physical prowess. Lots of trekkers seem to enjoy the challenge. I just enjoy the scenery, the culture, the people, and taking photos. I'm quite content to be as slow as I want to be, or need to be to get the photos I want, which is why I employ my own guide and porter so there's no pressure to arrive at a particular pre-booked lodge at the end of the day.
You've got a lovely website showing some amazing photos.
