Hey Albert. lighting is very flat on first 2. I like the 3rd imagee. just make sure cast shadow on pilars are different. Can you do master copy on this image ?http://www.erwinmadrid.com/images/1Megamind/031_2400color_script2.jpgtry to match 100% on this. really try to analyze why he used those colors too. I mean you don't have to know scientific reaason but try to maych the calue and color. Hold off on your painting. keep working on the sketch and design but you need to practice to get convincing warm and cool colors.
