Well, you're welcome @normazaro.
I think you've got a lot of talent and I hope you keep painting. From the look of things here and on your website, you'll be doing just that.
I'm guessing it depends on the subject matter, but how long typically do you think it takes to take a painting from concept to finished product? And do you sell your art? And if so, how is that going?
I know someone who tried their hand at making and selling their art, and it really didn't get off the ground. He was the main source of income in his family and so he didn't really have a chance, or time, to dedicate to it enough, I don't think. It seems like it would be a five year project, at least, and that if you are fortunate enough to make the right contacts. This was years ago, though, probably 15 or so. I'm sure there are many more ways to sell art now, particularly online, than there were then.
It is difficult to say how long an artwork takes, since I usually do more than one painting at the same time. I believe that one like the tiger has been at least a month. You are right now with the internet it is easier to show and sell our art. I publish some artworks at https://www.artfinder.com/norma-zaro#/ and I have sold some with them, but it is not easy, it is also difficult because I am from Argentina and I am far from the central art markets. Thank you very much for your interest.
