Another try, and a different medium

So I try adding color to my last picture, and I'm not happy with the result, therefore, I think I will try a new method.

Here is the oil painting that I believe is NOT working out...

However, I might go back, and keep trying it out. So here is another drawing, this time I'm attempting the same painting with watercolors, and pen and ink. I'm trying out masking fluid for the first time. Wish me luck! I'm using "Fineline Resist Pen."

And here it is, the new under painting, after applying the FineLine masking fluid, the idea is that all those areas that look blueish will be white.
