Wow! You have some really nice pieces here, GRMC. I think you could work a little more on light and color, but you´ve the rest pretty nailed up.
Your traditional paintings´re excellent, and a lot of them shows when you go more contemporary/conceptual, wich is great. I think sometimes the color and light you apply make the painting too flat, lacking depth, yet I see you´re working on it, shows in the current stylized challenge
Keep up the good job!!
