Thank you so much! : ) Wow, you're very talented. I was the same way, I only drew with pencils and then started colored pencils. My pencil sketches weren't near as nice as yours honestly. I have always wanted to paint but every attempt turned out horrible and fortinutely I found many great tutorials on youtube to give me guidance.

I'm not sure what you mean about fluency, but some good advice is just keep layering. Start with the background first and work your way to forward. Once one layer is dry put down another one. Start with dark colors first and then add the lighter colors. There's also a few ways to blend acrylic paint, blending colors lightly when they're still wet really helps, and then using washes.

A wash is just watered down paint, or, paint mixed with a gloss or matte medium will make it more transparent so that you can add light layers of color. Some painters do their painting in grey scale, with just black and white, and then add the color on top with washes. And of course practice practice, not all my paintings have turned out very nice, it's all still a journey of learning.

Maybe down the road I can do some posts to share the knowledge I have acquired the last couple of years. Thank you so much for looking at my painting I will check your work out more also : )
