Your work is all incredible and you've mastered watercolor painting. I believe you will do quite excellent, for being new you certainly have everything going well. Bird lovers will enjoy your work much.
I think you need to advise me more than I do you.
Though I agree that you do have a lot of images of similar birds, if you continue to upload more images of the same birds, you'll probably have to start titling them each differently. I know I love painting birds myself, and ironically enough, with watercolors, So I've had to start naming them, Blue Jay Greetings, Blue Jay Couple, Blue Jay Morning. I agree with separating them into galleries as well, maybe like one for songbirds, one for game birds, and so on as a start. Depends on how much you continue to do.
Just thought I'd share one of my favorites of your collection.
OH, and as a last thought being on FAA, you learn something new everyday from everyone. Work on your gallery everyday and you'll do well.
