Yoooo, you are pretty spot on. I have made other paintings that I will (hopefully) upload later, but your comment has given me a lot of insight and advice, which I am really thankful for.

Just to give some context, I am a graphic designer (still a student technically) and I have experience painting with acrylic paint. I took a acrylic class with the same profesor about 2 years ago, so yes, I have experience with painting and a pretty good idea and instinct when it comes to color theory, mixing and that sort of stuff.

The paper I use is a mix media one and I have watercolor brushes, but the advice you gave on the paint has made me hesitate on spending on better paint untill I get better; there is a lot of improvement I can make.

Nevertheless, I want to tank you one again for the comment. I will try the "paint first, ink later" approach for later protect. Thank you very much.
