New Abstract or New Figurative?

My last post was about a somewhat abstract work that I am improving. I have also been considering listing another older, abstract, colored pencil work, shown at the right. That image is entitled "Brownian Paisley" and is matted and framed and ready to sell. I am fairly committed to doing a lot more colored pencil, it is just a question of whether I should go in a more abstract direction or stay with the more figurative, surrealist works.

If I were to start creating a series, what should it be about? I will be doing a couple more for my Cell Series (see this link for one of them), but should I make it a larger series, or should I do something different? I would like to expand something into a series of works in order to unify the appearance of my shop. I would like for people to have an idea of what I am about from just a brief look--sometimes, that's all you get.

I have done a few long-faced cats, such as the one to the left, but I'm not sure if they would be that popular. I actually started them after completing a search on eBay of Self-Representing Artists whose items had already received bids ("cats" was among the more popular keywords, along with "nude" and "mini" which led me to briefly create the "Mini Nude Cat" series...). I love these guys, but they have not been successful sellers.

If any of my readers have any great ideas, I'd love to hear about it! Perhaps I will collect up all the ideas and create a poll here on my blog! Perhaps from there, I can create my first blog give-away contest! Who knows!
