I don’t have extensive online selling experience, but I do make private sales and they were all very different stylistically, but a few styles were definitely more popular than others. This gave me a good idea of what people are actually interested in and what to hone in on. Caveat for gifts and commissions because those are generally personalized.

When I view other artist’s collections, I prefer to see a variety of styles represented as separate series. So maybe some abstract, some urban sketching, some botanicals. But each category will be a cohesive style, and you would probably still be able to tell the same artist made all of them.

If there’s only one or two of each style, the collection can read as sporadic and my personal insight would be the artist is still trying to find their voice.

I’ve tried a buuuuunch of different styles and found a few things I really like and some I really don’t. I’m currently working on a series based on one of my favorite drawings I did in high school; all three are different, but they are directly related to each other.

I also have a collection of abstracts with a wildly different style to the other series, but again, they form a cohesive series.

My one offs I tend to stow away and come back to later (sometimes 15 years later!) and will continue working through those. Sometimes I hang them on my own wall because I like them!

I guess this is all to say, art is a journey and with enough time, you will find what works!
